Question

Simplify the following and write the answer in the exponential notation.

${\left(5g\right)}^7$

Answer 1

We know one of the law of exponents ,${\left(xy\right)}^b=x^b\times y^b$

Given expression, ${\left(5g\right)}^7$

Using the above law of exponents:

$\Rightarrow {\left(5g\right)}^7={\left(5\right)}^7\times {\left(g\right)}^7$

Hence, ${\left(5\right)}^7\times {\left(g\right)}^7$is the required exponential notation.
