5. Given


a^2-bw

You know that:

a=-1

b=2

w=-10

Replace these values into the expression:


(-1)^2-2\cdot(-10)

Following the order of operations, first, you have to solve the exponent and the multiplication:


1-(-20)

Both minus signs form a "double negative" when this happens, the signs cancel each other and turn into a plus sign, so that:


1+20

Next, solve the addition


1+20=21

The result of this operation is 21.
