Exponential form of 81/625

Vesnalui [34]

Step-by-step explanation:

Hey, there!!

you number is: 81/625

We know that,

81=9×9

and

625=25×25

and............................................................

9×9 means 9^2

and 25×25 means 25^2

so, the exponential form of the question is,

= $\frac{ {9}^{2} }{ {25}^{2} }$

{we simply find exponential form by finding their fraction}
