Question

Evaluate the expression. $$79-v^{3} \text { when } v=4$$

Short answer

The evaluated expression is 15.

Step-by-step solution

Substitute the given value into the expression

Replace \(v\) in the expression \(79 - v^3\) with the given value \(4\). That gives \(79 - 4^3\).

Simplify the expression

Calculate the cube of 4 which is \(4^3 = 64\). Substitute this value into expression, resulting in \(79 - 64\).

Subtract to find the final result

Now subtract 64 from 79, which equals 15. So, \(79 - 4^3 = 15\).
