Answer 2

To find : cube of $(\frac{-3}{4} )^{3}$

Solution :

• To find cube is to multiply number by itself three times .

• Therefore , to find cube of $(\frac{-3}{4} )^{3}$  we multiply $\frac{-3}{4}$ by itself three times .

         $(\frac{-3}{4} )^{3}$  $= \frac{-3}{4}\times \frac{-3}{4}\times \frac{-3}{4}$

                  $= \frac{-27}{64}$      

     Hence , cube of $(\frac{-3}{4} )^{3}$  is $\frac{-27}{64}$ .
