simplify (-5y^3)^3

Solution

simplify

(- 5 y^{3})^{3}

Solution

- 125 y^{9}

Solution steps

(- 5 y^{3})^{3}

Apply exponent rule:

(- a)^{n} = - a^{n},

if

n

is odd

(- 5 y^{3})^{3} = - (5 y^{3})^{3}

= - (5 y^{3})^{3}

Apply exponent rule:

(a \cdot b)^{n} = a^{n} b^{n}

(5 y^{3})^{3} = 5^{3} (y^{3})^{3}

= - 5^{3} (y^{3})^{3}

5^{3} = 125

= - 125 (y^{3})^{3}

Apply exponent rule:

(a^{b})^{c} = a^{b c},

assuming

a \geq 0

(y^{3})^{3} = y^{3 \cdot 3}

= - 125 y^{3 \cdot 3}

Multiply the numbers:

3 \cdot 3 = 9

= - 125 y^{9}
