Question

Evaluate expression 15+3(6/2)-4^2

Answer 1

Answer: 8

Step-by-step explanation:

$15 + 3(\frac{6}{2} )-4^2$

Using order of operations, solve parenthesis first

$15 + 3(3 )-4^2\\15 + 9-4^2$

Next, solve exponents. Note that only the '4' is getting raised to the '2' power, not '-2'

$15 + 9-(4^2)\\15 + 9-16$

Simplify

$15+9-16\\=8$
