Answer to Problem 34CCR

  $13,456$

Explanation of Solution

Given information :

The given information is, $a=3,b=5$ and $c=4$

Formula Used:

Concept of substitution.

Calculation :

  $\begin{array}{l}$ 4{(2a-c^3)}^2$$ =4{(2\times 3-4^3)}^2$$ =4{(6-64)}^2$$ =4{(-58)}^2$$ =4\times {(58)}^2$=13,456\end{array}$

Hence, $4{(2a-c^3)}^2=13,456$
