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
