Question

f(x)=(x-radx)^3 derivat va rooog​

Answer 1

f'(x)=((x-√x)³)'

$f'(x)=3(x-\sqrt{x} )^2\times (x-\sqrt{x} )'=3(x-\sqrt{x} )^2(1-\frac{1}{2\sqrt{x} })\\\\f'(x)= 3(x^2-2x\sqrt{x} +x)(1-\frac{\sqrt{x} }{2x} )= 3(x^2-2x\sqrt{x} +x)\times \frac{2x-\sqrt{x} }{2x}$

Asta daca ai scris corect sau daca am inteles corect f(x)

Folosim formulat (uⁿ)'=n×uⁿ⁻¹×u'
