1. Problem Description

We need to evaluate the expression (2)3÷(3)3×(6)2÷42(-2)^3 \div (-3)^3 \times (-6)^2 \div 4^2.

2. Solution Steps

First, we evaluate the powers:
(2)3=8(-2)^3 = -8
(3)3=27(-3)^3 = -27
(6)2=36(-6)^2 = 36
42=164^2 = 16
Now we substitute these values into the expression:
8÷(27)×36÷16-8 \div (-27) \times 36 \div 16
We can rewrite division as multiplication by the reciprocal:
8×127×36×116-8 \times \frac{1}{-27} \times 36 \times \frac{1}{16}
Rearrange to make it easier to compute:
827×3616\frac{-8}{-27} \times \frac{36}{16}
Simplify each fraction:
827×9×44×4\frac{8}{27} \times \frac{9 \times 4}{4 \times 4}
827×94\frac{8}{27} \times \frac{9}{4}
Simplify further:
2×43×9×94\frac{2 \times 4}{3 \times 9} \times \frac{9}{4}
23×44×99\frac{2}{3} \times \frac{4}{4} \times \frac{9}{9}
23×1×1\frac{2}{3} \times 1 \times 1
23\frac{2}{3}
