Question

When simplified, the value of the expression (15 - 11)^2 + square root 64 ÷ 4 is equal to _____.

Answer 1

Answer:

28

Step-by-step explanation:

Simplify:  (15 - 11)^2 + square root 64 ÷ 4

"Order of operations rules"  apply here.  Any work inside parentheses must be done first:

(15 - 11)^2 = (4)^2 = 16 (since exponentiation is the next operation in priority)

Then we have:

16 + square root 64 ÷ 4 and remember that we must do division and multiplication before addition or subtraction:

16 + sqrt(16)  +  4

Note that sqrt(16) is a POWER function which must be carried out before other operations, yielding:

16 + sqrt(64) + 4, or

16 + 8 + 4, or

(evaluating this from left to right):  24 + 4 =28
