simplify (3x^2)(3x)

Solution

simplify

(3 x^{2}) (3 x)

Solution

9 x^{3}

Solution steps

(3 x^{2}) (3 x)

Apply exponent rule:

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

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

= x^{2} \cdot 3^{1 + 1} x

Add the numbers:

1 + 1 = 2

= x^{2} \cdot 3^{2} x

Apply exponent rule:

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

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

= 3^{2} x^{2 + 1}

Add the numbers:

2 + 1 = 3

= 3^{2} x^{3}

3^{2} = 9

= 9 x^{3}
