If a = 2 and b = -3, find the value of a3 - b2. a.-31 b.-23 c.-1 d.15

Hello!

So let's first start out by solving the left side of the equation:

2 to the third power is 8

The right side now: -3 to the second power is -9

In total: 8- (-9)

So your answer is C) -1

I hope it helps!

Plug in -3 for b, and 2 for a

2^3 - (-3)^2

Remember to always follow PEMDAS. First, do the exponents

2^3 = 2 x 2 x 2 = 8

(-3)^2 = -3 x -3 = 9

Subtract

8 - 9 = -1

-1 is your answer

hope this helps

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
