i am doing problems for chemistry class, and some of them are Calculating square root/ Cube Root but some are 4 and 5 instead of 2 or 3. if in a problem the exponent is 4 or 5 how would i use my calculator to calculate the root?

    If it's 4th root, just take the square root twice. If the fifth root you can do it one of two ways but the easy way is to enter the number, punch y^x key (I'm sure your calculator has one), punch in 0.20 and the equal sign. For example, 5th root 32 = (32)^1/5 = (32)^0.2 = 2.0. For that matter, that's probably the easy way to take 4th root, too. Enter the number, hit the y^x key, and enter 0.25 and the = key.
    4th root 81 = (81)^1/4 = (81)^0.25 = 3.0.
