Question

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?

Answer 1

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.

Answer 2

thanks! that helped me solve the problems.
