Question 81952: can somone solve the following equations and show me how it was done! I'm as dumb as a post when it comes to this stuff. Any help would be great!
√x-2=1

√x3=27
3√x2=9

You can put this solution on YOUR website!
a:)take 2 over to the other side u get
√x=3
take the SQUARE(NOT SQUARE ROOT) of both sides
x=9
b:)√x3=27
take the SQUARE(NOT SQUARE ROOT) of both sides
3x=729
divide both sides by 3
x=243
c:)3√x2=9
divide both sides by 3
√x2=3
take the SQUARE(NOT SQUARE ROOT) of both sides
2x=9
divide both sides by 2
x=4.5
but listen u really need to learn this thing its pretty simple and it may come out in your tests n exams.
