Answer:
14. 27
16. 170
Explanation:
We must follow Order of Operations rules here. Work inside parentheses must be done first, then exponentiation, then multiplication and division, and finally addition and subtraction.
((5·7) - (8·4))³ becomes (35 - 32)³, or 3³, or 27.
16. 7² + ((46 - 7·2) + 2³)² becomes 7² + ((46 - 49) + 8)²
Again, do the work inside parentheses first:
7² + (3 + 8)² becomes 49 + 11², or 49 + 121, or, finally, 170
