How can you use this to help you write 6/8 as a decimal? Show your thinking to solve.

This is a required question
Express 6/8 as a decimal. *

Here's my little secret you can use to instantly transform any fraction to a decimal: Simply divide the numerator by the denominator:

= 6/8

= 6 ÷ 8

= 0.75

0.75

Step-by-step explanation:

6/8=3/4=0.75

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
