simplify x^2cos(pi)x

Solution

simplify

x^{2} cos (π) x

Solution

- x^{3}

Solution steps

x^{2} cos (π) x

Apply exponent rule:

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

x^{2} x = x^{2 + 1}

= cos (π) x^{2 + 1}

Add the numbers:

2 + 1 = 3

= cos (π) x^{3}

Simplify

cos (π) : - 1

= - 1 \cdot x^{3}

Multiply:

1 \cdot x^{3} = x^{3}

= - x^{3}
