Answer: 8
Step-by-step explanation:
[tex]15 + 3(\frac{6}{2} )-4^2[/tex]
Using order of operations, solve parenthesis first
[tex]15 + 3(3 )-4^2\\15 + 9-4^2[/tex]
Next, solve exponents. Note that only the '4' is getting raised to the '2' power, not '-2'
[tex]15 + 9-(4^2)\\15 + 9-16[/tex]
Simplify
[tex]15+9-16\\=8[/tex]
