Simplify 10 square root of x^15* square root of x^9

$10 \sqrt{x^{15}} \cdot \sqrt{x^{9}}$

Step 1

Rewrite $x^{15}$ as ${(x^{7})}^{2} x$ .

Factor out $x^{14}$ .

$10 \sqrt{x^{14} x} \cdot \sqrt{x^{9}}$

Rewrite $x^{14}$ as ${(x^{7})}^{2}$ .

$10 \sqrt{{(x^{7})}^{2} x} \cdot \sqrt{x^{9}}$

Step 2

Pull terms out from under the radical.

$10 (x^{7} \sqrt{x}) \cdot \sqrt{x^{9}}$

Step 3

Rewrite $x^{9}$ as ${(x^{4})}^{2} x$ .

Factor out $x^{8}$ .

$10 x^{7} \sqrt{x} \cdot \sqrt{x^{8} x}$

Rewrite $x^{8}$ as ${(x^{4})}^{2}$ .

$10 x^{7} \sqrt{x} \cdot \sqrt{{(x^{4})}^{2} x}$

Step 4

Pull terms out from under the radical.

$10 x^{7} \sqrt{x} \cdot (x^{4} \sqrt{x})$

Step 5

Multiply $x^{7}$ by $x^{4}$ by adding the exponents.

Move $x^{4}$ .

$10 (x^{4} x^{7}) \sqrt{x} \cdot \sqrt{x}$

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

$10 x^{4 + 7} \sqrt{x} \cdot \sqrt{x}$

Add $4$ and $7$ .

$10 x^{11} \sqrt{x} \cdot \sqrt{x}$

Step 6

Multiply $10 x^{11} \sqrt{x} \sqrt{x}$ .

Raise $\sqrt{x}$ to the power of $1$ .

$10 x^{11} ({\sqrt{x}}^{1} \sqrt{x})$

Raise $\sqrt{x}$ to the power of $1$ .

$10 x^{11} ({\sqrt{x}}^{1} {\sqrt{x}}^{1})$

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

$10 x^{11} {\sqrt{x}}^{1 + 1}$

Add $1$ and $1$ .

$10 x^{11} {\sqrt{x}}^{2}$

Step 7

Rewrite ${\sqrt{x}}^{2}$ as $x$ .

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{x}$ as $x^{\frac{1}{2}}$ .

$10 x^{11} {(x^{\frac{1}{2}})}^{2}$

Apply the power rule and multiply exponents, ${(a^{m})}^{n} = a^{m n}$ .

$10 x^{11} x^{\frac{1}{2} \cdot 2}$

Combine $\frac{1}{2}$ and $2$ .

$10 x^{11} x^{\frac{2}{2}}$

Cancel the common factor of $2$ .

Cancel the common factor.

$10 x^{11} x^{\frac{2}{2}}$

Rewrite the expression.

$10 x^{11} x^{1}$

Simplify.

$10 x^{11} x$

Step 8

Multiply $x^{11}$ by $x$ by adding the exponents.

Move $x$ .

$10 (x \cdot x^{11})$

Multiply $x$ by $x^{11}$ .

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

$10 (x^{1} x^{11})$

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

$10 x^{1 + 11}$

Add $1$ and $11$ .

$10 x^{12}$
