... × 3 × 3 × 4 × 4 × 4= 2 × 3 × 4 × 2 × 3 × 4 × 2 × 3 × 4= (2 × 3 × 4)3 2 × 3 × 4 is 24 , so 24 3= r3and r = 24 , choice (D).3. E Here we’ve got 2 equations, one with 2 variables and one with ... only 1 variable. If 2a = 10, then dividing both sides by 2 gives us a = 5. If a = 5, then a 2 – 16 = b 2 can be written 5 2 – 16 = b 2 , or 25 – 16 =b 2 , or 9 = b 2 . If b 2 is 9, then b must ... of the other choices are thingsthat the author never mentions at all.
