Simplify (4u^2)^(1/2)

${(4 u^{2})}^{\frac{1}{2}}$

Step 1

Simplify the expression.

Apply the product rule to $4 u^{2}$ .

$4^{\frac{1}{2}} {(u^{2})}^{\frac{1}{2}}$

Rewrite $4$ as $2^{2}$ .

${(2^{2})}^{\frac{1}{2}} {(u^{2})}^{\frac{1}{2}}$

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

$2^{2 (\frac{1}{2})} {(u^{2})}^{\frac{1}{2}}$

Step 2

Cancel the common factor of $2$ .

Cancel the common factor.

$2^{2 (\frac{1}{2})} {(u^{2})}^{\frac{1}{2}}$

Rewrite the expression.

$2^{1} {(u^{2})}^{\frac{1}{2}}$

Step 3

Evaluate the exponent.

$2 {(u^{2})}^{\frac{1}{2}}$

Step 4

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

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

$2 u^{2 (\frac{1}{2})}$

Cancel the common factor of $2$ .

Cancel the common factor.

$2 u^{2 (\frac{1}{2})}$

Rewrite the expression.

$2 u^{1}$

Step 5

Simplify.

$2 u$
