Question

How do you solve 7 exponent 0.8

Answer 1

4.74; Explanation is as follows

Explanation:

When you raise a number to a fractional power, it is the same as taking a root of that number. Here's what I mean:

We know that .8 is the same as 4/5, so 7^.8 power is the same as 7^4/5 power!

`7^(4)/(5) =\sqrt[5]{7^4}`

The above equation is the same as 7 raised to the .8th power! Now to solve, we do the following:

`=\sqrt[5]{7^4} \\=\sqrt[5]{7*7*7*7} \\= \sqrt[5]{2401} \\=4.74`

So that is how you raise 7 to the .8th power!
