in the expression xy^2 , the value of X and y decreased by 25 percent

1.	in the expression xy^2 , the value of X and y decreased by 25 percent , the value of expression is ?
Answer» Answer: LET X and Y DENOTE the new values of x and y respectively. Then, X = 80% of x = 4x5 Y = 80% of y = 4y5 ∴XY2=4x5×(4y5)2=4x5×16y25=64125xy2 Decrease in the value : =(xy2−64125xy2)=61125xy2 ∴ Decrease % =61125xy2=(61xy2125×1xy2×100)%=48.8% Step-by-step explanation: i think it will help you please MARK me as bralient

Answer:

LET X and Y DENOTE the new values of x and y respectively.

Then, X = 80% of x = 4x5

Y = 80% of y = 4y5

∴XY2=4x5×(4y5)2=4x5×16y25=64125xy2

Decrease in the value :

=(xy2−64125xy2)=61125xy2

∴ Decrease %

=61125xy2=(61xy2125×1xy2×100)%=48.8%
