Question

"What is the value of-3|15-s|+2^3 when s-=3"?

Answer 1

You probably made a typing error in writing s = -3 and wrote s - = 3 instead.

The given expression is:

$-3|15-s|+ 2^{3} \\ \\ -3|15-s|+8$

Substituting the given value of s in the previous equation, we get:

$-3|15-(-3)|+8 \\ \\ =-3|15+3|+8 \\ \\ =-3|18|+8 \\ \\ =-54+8 = -46$

Thus the value of given expression becomes -46 for s = -3
