hey can u guys check this out.

differentiate with respect to x.

y = 2 / (2x + 3)^4

i got -16/ (2x+3)^5

i don't think it right. regards.

= d/dx 2(2x+3)^-4

= 2 x -4 x 2 (2x+3)^-5

= -16(2x+3)^-5

=-16/(2x+3)^5

Have more confidence in yourself!

Or you could do it the longer way using quotient rule

y' = 0 - [4(2x+3)³*2*2] / (2x+3)⁸
= -16 / (2x+3)⁵
