Simplify fully
a) 16x²y + 8x
b)
21x³y
7xy

The simplified form of the expression are as follows;
a. 2xy
b. 3x²
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
