turunan pertama dari f(x) =x⅞+2x⅝-4x³+2 adalah

7/8x^-1/8 + 10/8 x^-3/8 - 12x²
°Magnolia1 here fot help you
just follow and hope you feel satisfy°

f(x) = x^7/8 + 2x^5/8 - 4x^3 + 2
f'(x) = 7/8 x^(7/8 - 1) + 2 . 5/8 x^(5/8 - 1) - 4.3x^(3 - 1)
= 7/8 x^(-1/8) + 5/4 x^(-3/8) - 12x^2

= 7/(8x^1/8) + 5/(4x^3/8) - 12x^2
