## geeferz 3 years ago What is the fifth root of 12^4

1. geoffb

Remember, roots are just exponents that are 1/x. So, square root is to the power of 1/2. Cube root is to the power of 1/3. Therefore, if you want the fifth root, you can put it to the power of 1/5. $(12^{4})^{\frac{1}{5}}$

would i need a calculator to figure out the final answer?

3. geoffb

Yes, you would. It would be $$12^{\frac{4}{5}}$$ or $$12^{0.8}$$. Definitely can't be done in your head.
