Question

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

Answer 1

Answer:

B)  $b^{8}$.

Step-by-step explanation:

Given  : $\frac{b^{10}}{b^{2}}$.

To find : simplify.

Solution : We have given  $\frac{b^{10}}{b^{2}}$.

By the quotient property of exponential  :  $\frac{x^{a}}{x^{c}} = x ^{a -c}$.

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

$\frac{b^{10}}{b^{2}}$ = $b^{10 -2}$.

$\frac{b^{10}}{b^{2}}$ =  $b^{8}$.

Therefore, B)  $b^{8}$.

Answer 2

Answer:

the answer here is B

Step-by-step explanation:

Step  1  :

           b10

Simplify   ———

           b2  

Dividing exponential expressions :

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

Final result :

 b8
