If P = 4x2, T = 5x and R = 5y, then = ..........

Here we have P = 4x2 ,T = 5x and R = 5y.Therefore the product of P,T and R will be PTR = (4x2)×(5x)×(5y) = 100x3yHence is equal to i.e. x3y.

If P = 4x², T = 5x and R = 5y, then = ..........

Here we have P = 4x² ,T = 5x and R = 5y.

Therefore the product of P,T and R will be PTR = (4x²)×(5x)×(5y) = 100x³y

Hence is equal to i.e. x³y.
