Question

2 to the power of 3 parentheses 30 divided by 5 plus 9

Answer 1

104

Explanation:

2x2x2(30/5 +9)

2x2x2(6+9)

2x2x2(13)

2x2x2x13=104

Answer 2

120

Explanation:

Simplify the following:

2^3 (30/5 + 9)

The gcd of 30 and 5 is 5, so 30/5 = (5×6)/(5×1) = 5/5×6 = 6:

2^3 (6 + 9)

6 + 9 = 15:

2^3×15

2^3 = 2×2^2:

2×2^2×15

2^2 = 4:

2×4×15

2×4 = 8:

8×15

8×15 = 120:

Answer: 120
