Answer:

she wrote

(-2)^3= 8\\instead\ of\ (-2)^3= -8

Step-by-step explanation:

For proper understanding let us format the question properly

Given  the expression

=(-2)^3(6-3)-5(2+3)\\=(-2)^3(3)-5(5)\\=8(3)-25\\= 24-25= -1

Sandy's error can be observed in the second line of the solution where she made the mistake of writing (-2)^3= 8  instead of (-2)^3= -8

hence the solution is supposed to be

=(-2)^3(6-3)-5(2+3)\\=(-2)^3(3)-5(5)\\=-8(3)-25\\= -24-25= -49

Answer:

3 1/8 or 3.125.
