Question 179(iii)

Express each of the following in exponential form.
$\frac{400}{3969}$

Answer 1

Given, $\frac{400}{3969}$
Since, $\left(20\right)\times \left(20\right)=400=(20{)}^{2}and63\times 63=3969=(63{)}^2$
Exponential form of $\frac{400}{3969}=-\frac{(20{)}^2}{(63{)}^2}={\left(\frac{20}{63}\right)}^2$
