Question

Evaluate (c − b2) + a3 for a = –3, b = –2, and c = –4.

Answer 1

`-35`

Explanation:

we have the expression

`(c-b^(2))+a^(3)`

For a=-3,b=-2 and c=-4

Substitute the given values of a,b and c to evaluate the expression

`(-4-(-2)^(2))+(-3)^(3)`

`(-4-(4))+(-27)`

Remember that

`(+1)(-1)=-1`

`(-1)(-1)=+1`

`(-8-27)`

`-35`
