Question

1. \\(\frac{(9 - 15)^2 \cdot (7 - 2^2)}{\sqrt{49} + 5} - |-5|\\)

Explanation:

Step1: Calculate parentheses/exponents

$(9-15)^2=(-6)^2=36$, $2^2=4$, $7-4=3$, $\sqrt{49}=7$, $|-5|=5$

Step2: Compute numerator/denominator

Numerator: $36×3=108$; Denominator: $7+5=12$

Step3: Do division then subtraction

$\frac{108}{12}=9$; $9 - 5=4$
