## anonymous one year ago Radical Equation help?

1. UsukiDoll

If I end up stalling in the middle, it means my batteries in my wireless mouse are dead and I need to replace them

2. anonymous

Select whether the equation has a solution or not. $\sqrt[3]{x-5}-2=0$

3. anonymous

Ok

4. UsukiDoll

ok so remember that we need all variable need to be on the left that 2 needs to go on the right.

5. anonymous

Ok so its gonna be the radical thing = 2

6. UsukiDoll

yeah that cube root =2

7. UsukiDoll

$\large \sqrt[3]{x-5}=2$

8. anonymous

x-5=8

9. UsukiDoll

so now to get rid of that cube root... blah let's just rearra...........you've taken ^3 on both sides... impressive.. ok.. now solve for x

10. anonymous

Ok so x=13 that wasn't so hard I just wasn't sure since that little number 3 is new to me even though i know what it means

11. UsukiDoll

that means cube root

12. UsukiDoll

plug x = 13 back into the equation and see what happens (doesn't have to be the original equation this time)

13. anonymous

Ok I got 8=8 and 0=0 depending on how you put it in

14. UsukiDoll

that indicates that you've done the problem correctly

15. anonymous

ok cool thanks

16. starwars18

guess this was solved. don't hate on math :)

I'll try lol
