According to the given expression, the value of b if 
is -1 and + 1
Indices are expressed using exponents and bases. Some of the useful laws of indices are:
Given the expression;
This can also be expressed as:
![b^2=\frac{1}{b^{10}}\\b^2 \times b^{10} =1\\b^{2+10} =1\\b^{12}=1\\b=\pm\sqrt[12]{1}\\b=\pm1](https://tex.z-dn.net/?f=b%5E2%3D%5Cfrac%7B1%7D%7Bb%5E%7B10%7D%7D%5C%5Cb%5E2%20%5Ctimes%20b%5E%7B10%7D%20%3D1%5C%5Cb%5E%7B2%2B10%7D%20%3D1%5C%5Cb%5E%7B12%7D%3D1%5C%5Cb%3D%5Cpm%5Csqrt%5B12%5D%7B1%7D%5C%5Cb%3D%5Cpm1)
Hence the value of b from the given indices is -1 and + 1

The number which divides any other numbers
Answer:
No, they are not equivalent
Step-by-step explanation:
8x + 3(x + y)
8x + 3x + 3y
11x + 3y
7x + 7y + 4x + 4y
11x + 11y
They are not equivalent because in one of the equations, the like terms add up to 11y which is different from the other equation which adds up to 3y.
I hope this helps.
Hello! I believe the answer to your question is C (hours). If t is the amount of time it takes, hours is a unit of time, therefore I assume that would be your answer. :)
Answer:
78.54 m
Step-by-step explanation:
To obtain how much circular fence, we obtain the Circumference of the circular playground.
The Circumference of a circle, C = 2*pi*r
pi = 3.14 ; r = diameter / 2 = 25 /2 = 12.5 m
C = 2 * 3.14 * 12.5
C = 78.539816
Hence, the fencing which need to go up is ;
78.54 m
