Question

Evaluate the expression below for a=2, b=3, and c= -2.



a+(b-c)^2

Answer 1

3

Explanation:

2+(3−2)2

=2+12

=2+1

3

Answer 2

the answer is
`27`

Explanation:

First, you need to substitute a, b, and c for their sums

So your new problem should look like this...
`2+\left(3-\left(-2\right)\right)^2`

Then you can begin solving this problem using PEMDAS

So first you're going to start w/ the parenthesis...
`3-\left(-2\right)` which equals 5

Next, you're going to calculate the exponents, so it should look like this...
`5^(2)` which equals
`25`

So now your problem should look like this...
`5+25` which equals
`27`

So your answer is
`27`

hope this helps!
