Problem Solving (PS) | Re: Simplify (16^3-15^3)(16^2-15^2)

We can focus on units digits to solve the question.

Since 6 raised to an exponent always produces a units digit of 6, and 5 raised to an exponent always produces a units digit of 5, we have the units digit of the expression as:

(6 - 5)(6 - 5) = 1 x 1 = 1

Thus, the correct answer must have a units digit of 1. Thus, the answer is 22,351.

Answer: B
