Calculate 4x^5- 4y, where x=-3, y=5.

Question:

Calculate {eq}4x^5- 4y, {/eq} where {eq}x=-3, y=5 {/eq}.

Maths

To solve an equation, we follow the rule of BODMAS (Bracket, Off, Division, Multiplication, Addition, Subtraction). If there are multiple mathematical operations in an equation, we perform the operations in order of BODMAS.

{eq}\begin{align} { 4x^5 - 4y \\ = 4(-3)^5 - 4*5 \\ = 4*(-1)^5*3^5 - 20 \\ = 4*(-1)*243 - 20 \\ = - 972 - 20 \\ = -992 } \end{align} {/eq}
