Question

Choose the correct simplification of the expression 4 times b all over a to the power of negative 10.

Answer 1

4 over a to the 10th power times b

Answer 2

Answer:

Option B is correct that is $4a^{10}b$

Step-by-step explanation:

Given Expression: $\frac{4\times b}{a^{-10}}$

We have to simplify the Given Expression.

We use the following law of exponent,

$x^{-a}=\frac{1}{x^a}$

Consider,

$\frac{4\times b}{a^{-10}}$

$=4\times b \times a^{10}}$

$=4a^{10}b$

Therefore, Option B is correct that is $4a^{10}b$
