Question

if a = -3 and b = 2 find the value of a raise to the power 3 - b raises to the power 2+2ab+7

Answer 1

Here's the answer :)

Given :

a = -3

b = 2

Equation :
$\sf{ {a}^{3} - {b {}^{2} }^{} + 2ab + 7}$

Putting the values of a and b.

$\sf {{( - 3)}^{3} - 2 {}^{2} + 2 \times -3 \times 2 +7}$

$\sf{ - 27 + 4 + ( - 12) + 7}$

$\sf{- 31 - 12 + 7}$

$\sf{ - 31 - 5} \\ \\ \sf{ = - 36}$

Thus,
Value of the given Equation = (- 36).

Thanks!
