b. 3x²

How to simplify an equation?

The equation can be simplified as follows:

16x²y ÷ 8x

Therefore,

16x²y ÷ 8x = 16x²y / 8x = 2 × 8 × x × x × y / 8 × x = 2xy

21x³y / 7xy = 3 × 7 × x × x × x × y / 7 × x × y = 3x²

Therefore, the simplified form of the expression are as follows;

16x²y ÷ 8x = 2xy

21x³y / 7xy = 3x²
