How do you factorise x^2+7x?

➷  You find the largest value or 'letter' that is shared by both

In this case, you can see the largest common value shared by x^2 and 7x is simply just 'x'

Place 'x' outside the parenthesis and inside the parenthesis place the values you would multiply by x to reach the original expression

Your answer is:

x(x + 7)

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)
