Simplify x^2*3x

$x^{2} \cdot 3 x$

Step 1

Rewrite using the commutative property of multiplication.

$3 x^{2} x$

Step 2

Multiply $x^{2}$ by $x$ by adding the exponents.

Move $x$ .

$3 (x \cdot x^{2})$

Multiply $x$ by $x^{2}$ .

Raise $x$ to the power of $1$ .

$3 (x^{1} x^{2})$

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$3 x^{1 + 2}$

Add $1$ and $2$ .

$3 x^{3}$
