Question

Simplify b^10/b^2
A.b^-2
B.b^8
C.b^5
D.b^-8

Answer 1

the answer here is B

Explanation:

Step 1 :

b10

Simplify ———

b2

Dividing exponential expressions :

1.1 b10 divided by b2 = b(10 - 2) = b8

Final result :

b8

Answer 2

B)
`b^(8)`.

Explanation:

Given :
`(b^(10))/(b^(2))`.

To find : simplify.

Solution : We have given
`(b^(10))/(b^(2))`.

By the quotient property of exponential :
`(x^(a))/(x^(c)) = x ^(a -c)`.

Here , x = b , a = 10 , c = 2.

`(b^(10))/(b^(2))` =
`b^(10 -2)`.

`(b^(10))/(b^(2))` =
`b^(8)`.

Therefore, B)
`b^(8)`.
