Question

Evaluate 3(a + b + c)squared for a = 2, b = 3, and c = 4.

a. 54
b. 243
c.729

Please add solution thanks.

Answer 1

So, we have to sum the three numbers, square the result, and then multiply the result by three.

We have

`a+b+c = 2+3+4 = 9`

If we square this result, we get

`9^2=81`

If we multiply this by 3, we have

`81 \cdot 3 = 243`
