Write each expression below in radical form and compute the value without using a calculator.

gregori [183]

Assuming that an exponentiation sign is missing, all you need to know is that rational exponents work like this:

$a^{\frac{b}{c}}=\sqrt[c]{a^b}$

So, you have

$25^{\frac{5}{2}}=\sqrt{25^5}=\sqrt{(5^2)^5}=5^5$

And similarly,

$81^{\frac{7}{4}}=\sqrt[4]{25^7}=\sqrt[4]{(3^4)^7}=3^7$
