find the derivative of y=(x²+51/x²)²
my steps:
y'=2[x²+5x^(2)](2x+2x)
=4x³+20x4x^(1)
but the answer given is 4x³+20x+20/x³4/x^5
why am i wrong?

Best ResponseYou've already chosen the best response.0it is derivative of y = (x^2 + 5  1)^2 * (x^2)

Best ResponseYou've already chosen the best response.1the derivative of x^(2) is not 2x it's 2x^3

Best ResponseYou've already chosen the best response.1so just change your 2x there with 2x^3 and you're fine. redo the rest of the solution
