simplify x^2(r(r-1)x^{r-2})

Solution

simplify

x^{2} (r (r - 1) x^{r - 2})

Solution

r x^{r} (r - 1)

Solution steps

x^{2} (r (r - 1) x^{r - 2})

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

x^{2} x^{r - 2} = x^{2 + r - 2}

= r (r - 1) x^{2 + r - 2}

Simplify

2 + r - 2 : r

= r x^{r} (r - 1)
