Find the Inverse 10 root of x

$\sqrt[10]{x}$

Step 1

Interchange the variables.

$x = \sqrt[10]{y}$

Step 2

Solve for $y$ .

Rewrite the equation as $\sqrt[10]{y} = x$ .

$\sqrt[10]{y} = x$

To remove the radical on the left side of the equation, raise both sides of the equation to the power of $10$ .

${\sqrt[10]{y}}^{10} = x^{10}$

Simplify each side of the equation.

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[10]{y}$ as $y^{\frac{1}{10}}$ .

${(y^{\frac{1}{10}})}^{10} = x^{10}$

Simplify the left side.

Simplify ${(y^{\frac{1}{10}})}^{10}$ .

Multiply the exponents in ${(y^{\frac{1}{10}})}^{10}$ .

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

$y^{\frac{1}{10} \cdot 10} = x^{10}$

Cancel the common factor of $10$ .

Cancel the common factor.

$y^{\frac{1}{10} \cdot 10} = x^{10}$

Rewrite the expression.

$y^{1} = x^{10}$

Simplify.

$y = x^{10}$

Step 3

Replace $y$ with $f^{- 1} (x)$ to show the final answer.

$f^{- 1} (x) = x^{10}$

Step 4

Verify if $f^{- 1} (x) = x^{10}$ is the inverse of $f (x) = \sqrt[10]{x}$ .

To verify the inverse, check if $f^{- 1} (f (x)) = x$ and $f (f^{- 1} (x)) = x$ .

Evaluate $f^{- 1} (f (x))$ .

Set up the composite result function.

$f^{- 1} (f (x))$

Evaluate $f^{- 1} (\sqrt[10]{x})$ by substituting in the value of $f$ into $f^{- 1}$ .

$f^{- 1} (\sqrt[10]{x}) = {(\sqrt[10]{x})}^{10}$

Rewrite ${\sqrt[10]{x}}^{10}$ as $x$ .

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[10]{x}$ as $x^{\frac{1}{10}}$ .

$f^{- 1} (\sqrt[10]{x}) = {(x^{\frac{1}{10}})}^{10}$

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

$f^{- 1} (\sqrt[10]{x}) = x^{\frac{1}{10} \cdot 10}$

Combine $\frac{1}{10}$ and $10$ .

$f^{- 1} (\sqrt[10]{x}) = x^{\frac{10}{10}}$

Cancel the common factor of $10$ .

Cancel the common factor.

$f^{- 1} (\sqrt[10]{x}) = x^{\frac{10}{10}}$

Rewrite the expression.

$f^{- 1} (\sqrt[10]{x}) = x$

Simplify.

$f^{- 1} (\sqrt[10]{x}) = x$

Evaluate $f (f^{- 1} (x))$ .

Set up the composite result function.

$f (f^{- 1} (x))$

Evaluate $f (x^{10})$ by substituting in the value of $f^{- 1}$ into $f$ .

$f (x^{10}) = \sqrt[10]{x^{10}}$

Remove parentheses.

$f (x^{10}) = \sqrt[10]{x^{10}}$

Pull terms out from under the radical, assuming positive real numbers.

$f (x^{10}) = x$

Since $f^{- 1} (f (x)) = x$ and $f (f^{- 1} (x)) = x$ , then $f^{- 1} (x) = x^{10}$ is the inverse of $f (x) = \sqrt[10]{x}$ .

$f^{- 1} (x) = x^{10}$
