Question

Find dy/dx

1. If y = x^4 + 1/x^2 - x

Find dy/dx

Answer 1

Hey mate....^_^

Here's ur ans.⤵

========================
$dy \div dx \: = nx^{n + 1}$

$dx {}^{4} \div dx \: \: + dx {}^{ - 2} \: \div dx$

$y \: = x {}^{4} + 1 \div x {}^{2} - x$

$d(x {}^{4} + 1 \div x {}^{2} - x) \: \: \: \: \div \: \: \: dx \: \: \: - dx \: \div dx$

$using \: the \: above \: fomula$

$4 {x}^{3} - \: 2 \: {x}^{ - 3} - 1$

✌ Hope it helps
