Question

Given 81r24 where a and b are positive integers. Work out a and b.

A) a = 8, b = 4
B) a = 9, b = 3
C) a = 12, b = 2
D) a = 16, b = 1

Answer 1

To work out the values of a and b in the expression 81r24, we need to recognize that 81 is equal to 9 × 9 and that 24 is equal to 8 × 3. So, a = 9 and b = 3. Therefore, the correct answer is option B) a = 9, b = 3.
