Simplify (9x^8)^(1/2)

${(9 x^{8})}^{\frac{1}{2}}$

Step 1

Simplify the expression.

Apply the product rule to $9 x^{8}$ .

$9^{\frac{1}{2}} {(x^{8})}^{\frac{1}{2}}$

Rewrite $9$ as $3^{2}$ .

${(3^{2})}^{\frac{1}{2}} {(x^{8})}^{\frac{1}{2}}$

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

$3^{2 (\frac{1}{2})} {(x^{8})}^{\frac{1}{2}}$

Step 2

Cancel the common factor of $2$ .

Cancel the common factor.

$3^{2 (\frac{1}{2})} {(x^{8})}^{\frac{1}{2}}$

Rewrite the expression.

$3^{1} {(x^{8})}^{\frac{1}{2}}$

Step 3

Evaluate the exponent.

$3 {(x^{8})}^{\frac{1}{2}}$

Step 4

Multiply the exponents in ${(x^{8})}^{\frac{1}{2}}$ .

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

$3 x^{8 (\frac{1}{2})}$

Cancel the common factor of $2$ .

Factor $2$ out of $8$ .

$3 x^{2 (4) \frac{1}{2}}$

Cancel the common factor.

$3 x^{2 \cdot 4 \frac{1}{2}}$

Rewrite the expression.

$3 x^{4}$
