Question

Help on #51 please !!

Answer 1

53. ±6

51. 2

Explanation:

According to the Order of Operations [GEMS\BOMDAS\PEMDAS etc.], in this case, evaluate everything in grouping symbols first, then evaluate the exponents to avoid confusion:

`\sqrt{(32 + {2}^(3) - 4)} = √(32 + 8 - 4) = √(36) = ±6 \\ \\ (17 - 11 + {4}^(2)) / 11 = (17 - 11 + 16) / 11 = \\ \\ 22 / 11 = 2`

I am joyous to assist you anytime.
