Thread: Raising to the power of a fraction

1. Raising to the power of a fraction

Hi it is probably easy for most of you but I am stuck on a question and I need to raise a number to the power of a fraction.
How do I go about inputting it on a calculator I have a Ti 36 x.

For instance 5 to the power of 2/5

2. $\displaystyle 5^{\frac{2}{5}}$ would be the 5th root if you like of 2 then square this number..power 2. so:

by 5th root i mean 2 to the power of ? =5

$\displaystyle (^{5}\sqrt{5})^{2}$

which would be 1.9036.. on a calc
on my calc i press shift then 'x to the power button' and that usually does the trick..

Try to type :

5^(2/5)

4. $\displaystyle x^{\dfrac{a}{b}}\implies$$\displaystyle x$ ^ $\displaystyle \left( a \div b \right)$

If I have the model of the calculator right type in
$\displaystyle 5~x^y~(~2/5~)~\text{enter}$
