Question

what will be the change in value of xy/(x^3) when x is reduced by 50%

Answer 1

@amistre64 any idea on how to go about this one?

Answer 2

\(xy/x^3 = y/x^2\)

Answer 3

call that f(x)

f(x) = y/x^2 -----(1)

Answer 4

f(.5x) = y/(.5x)^2 = y/.25(x^2)------- (2)

Answer 5

take (1)/(2) to find the change in expression

Answer 6

f(x) / f(.5x) = ?

Answer 7

@ganeshie8 0.25=25%

Answer 8

yeah it reduces the value of expression to 25 %

or

f(x) reduces by 75 %


both are same

Answer 9
