0²/₃ = 0 but 0⁻²/₃ is undefined because 1/0 is undefined.
Consider 0²/₃. So here, 0 has a positive power though a rational at that.
Any positive powers of 0 is considered as 0 itself. This expression also means that the square of the cubic root of zero. We know that cubic root of 0 is 0 and 0² = 0 itself. So we can conclude that 0²/₃ = 0.
Now consider 0⁻²/₃ .
We have [tex]a^{-b}=\frac{1}{a^b}[/tex].
So here, 0⁻²/₃ = [tex]\frac{1}{0^{\frac{2}{3}} }[/tex]
From the previous case, 0²/₃ = 0
So we get 0⁻²/₃ = 1/0, which is undefined.

What is defined as the cuboid?A cuboid is a 3 solid with six (rectangular) faces, eight vertices, and twelve edges.
A cuboid is defined by three dimensions: length, width, and height. A perfect cuboid is categorized as a cuboid with integer edges.A cuboid's total surface area (TSA) is the total of the areas of all of its rectangular faces.Total Surface Area (TSA) = 2(lb + bh + hl) sq.units
where, i is the length, b is the breadth and h is the height.
The given values are;
length l = 12 ft
breadth b = 10 ft
height h = 16 ft
Put the values in the formula;
Total Surface Area (TSA) = 2(12×10 + 10×16 + 16×12)
= 2×(120 + 160 +192)
= 2×(472)
Total Surface Area (TSA) = 1504
Now, reduce the area of the floor as it is not to be painted;
Painted area = Total Surface Area (TSA) - area of floor
= 1504 -12×10
Painted area = 3,008 sq. ft
The area covered by 1 paint can is 200 sq. ft.
Can required = total painted area/painted area by one can
Can required = 3,008/200
= 14.44
Can required = 15 (as half can is not considered)
Therefore, the area painted is 3,008 sq. ft with the total number of cans as 15.

What is (f⁰g)(-3) for the functions f and g defined in Problem 3 ?
f(g(-3)) = f(6) = 9.
For composing functions like this, we'll work from the inside out. First, find g(-3) by plugging x = -3 into the function g(x):
g(x) = |x - 3|
g(-3) = |-3 - 3|
g(-3) = |-6|
g(-3) = 6
Now we can replace g(-3) with 6 in the function composition to get f(g(-3)) = f(6). Find f(6) by plugging x = 6 into the function f(x):
f(x) = x + 3
f(6) = 6 + 3
f(6) = 9
So, f(g(-3)) = f(6) = 9.

log 2 x+log x=11
log 2x + log x = 11 => x = 223600, by properties of logarithm.
What is Logarithm?The opposite of exponentiation is the logarithm.This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.Now,
log (2x) + log (x) = 11
=> log [(2x)(x)] = 11 (as log (a) + log (b) = log (ab))
=> log (2x²) = 11
Since, generally the base of log is 10, raising them to 10
=> [tex]10^{log_{10}(2x^{2})} = 10^{11}[/tex]
=> 2x² = 10¹¹
=> x² = [tex]\frac{10^{11}}{2}[/tex]
=> x = [tex]10^{5}\sqrt{\frac{10}{2}} = 10^{5}\sqrt5[/tex]
=> x = 10⁵ (2.2360)
=> x = 223600
Hence, log 2x + log x = 11 => x = 223600, by properties of logarithm.

find the next four terms of the geometric sequence given the a1=2x r=x³
Answer: [tex]2\text{x}^4, \ 2\text{x}^7, \ 2\text{x}^{10}, \ 2\text{x}^{13}[/tex]
===========================================================
Explanation:
The first term is [tex]a_1 = 2\text{x}[/tex] and the common ratio is [tex]r = \text{x}^3[/tex]
To get the second term, we multiply the first term by that common ratio
[tex]a_2 = a_1*r = 2\text{x}*\text{x}^3 = 2\text{x}^4[/tex]
Repeat a similar idea for the third term
[tex]a_3 = a_2*r = 2\text{x}^4*\text{x}^3 = 2\text{x}^{4+3} = 2\text{x}^7[/tex]
and the fourth term is
[tex]a_4 = a_3*r = 2\text{x}^7*\text{x}^3 = 2\text{x}^{7+3} = 2\text{x}^{10}[/tex]
The fifth term is
[tex]a_5 = a_4*r = 2\text{x}^{10}*\text{x}^3 = 2\text{x}^{10+3} = 2\text{x}^{13}[/tex]
Something to notice: The exponents of the first five terms are: 1, 4, 7, 10, 13. The sequence of exponents is arithmetic even though the original underlying sequence is geometric.
The reason why the exponent sequence is arithmetic is because we keep multiplying by [tex]\text{x}^3[/tex], and hence we keep adding 3 to each exponent to get the next exponent.
-----------------------------------------
To summarize, the first five terms are:
[tex]2\text{x}, \ 2\text{x}^4, \ 2\text{x}^7, \ 2\text{x}^{10}, \ 2\text{x}^{13}[/tex]
We will ignore the first term 2x since your teacher wanted you to find the next four terms after that first term (i.e. term2 through term5).

Step-by-step explanation:
[tex]\mathrm{(Round)~If~x < 5,~x=y.0}[/tex]
→ y is the number, for instance, 60.0 since 63.0 in the ones/tenths place is less than 5 or 0.5
[tex]20 \times 70 = 1,400[/tex]
→ imagine the newly rounded 73 as 2 × 7 which is 140, but it's 2 more 0's, so it's 1,400.
[tex]\bold{77}\\18|1,400\\18 \times 7 = 126\\140 - 126 = 14\\18 \times 7 = 126\\140 - 126 = 14[/tex]
→ long division was performed. for each time a 0 appeared in 14 when 140 was subtracted by 126(18 • 7), a zero was either borrowed from 1,400 or dropped from 1,400 which became our remainder of 14 both ways around.
→ 77 is close to 75 but not below 5, so it round to 80. therefore, your estimate result is 80.
(The exact result is 81.1)
