How do you calculate in your calculator 1.5 raised to the fifth power?

Answer 1

Ideally, you would use the power key. It is usually labelled as xy or as yx. Typically, you would press:

1.5 (power) 5 (equal).

If you don't have a scientific calculator, you can also calculate:

1.5 x 1.5 x 1.5 x 1.5 x 1.5

Please note that this latter method doesn't work for fractional powers; if you need those, you certainly need a scientific calculator. The calculator included in Windows has an option to change to a scientific calculator.
