Answer 2

Answer:

The required exponential form is $x=-(\frac{9}{16})^2$

Step-by-step explanation:

Given : Expression $-\frac{81}{256}$

To find : Express rational numbers in exponential form ?

Solution :

Let $x=-\frac{81}{256}$

Exponential form is when the number written in the power.

We know, $81=9^2$ and $256=16^2$

Substitute the values,

$x=-\frac{9^2}{16^2}$

$x=-(\frac{9}{16})^2$

Therefore, The required exponential form is $x=-(\frac{9}{16})^2$
