$2(4n-3)^\frac{ 1 }{ 2 }-1=0$ How do you think you should start?

4. shaniehh

apply the 1/2

5. anonymous

There are 2 things to do before that. First you have to add the 1 to both sides. Then divide both sides by 2

i dont understand

so 4 + 1 and 3 + 1

no. ignore the stuff in parentheses for now. All of that is under an exponent. Think of solving an equation as reverse order of operations (PEMDAS/BEDMAS). So you need to deal with the addition and subtraction first. (that's moving the 1 to the right side of the equal sign.) Then we'll do multiplication and division (that's moving the 2 to the right side of the equal sign). Then we'll do the exponent (the 1/2) An then the last steps are dealing with the 4n - 3 inside parentheses.|dw:1440866106931:dw|

So it's -1 + 1 on the left side and 0 + 1 on the righ

*right

@peachpi whats next

15. anonymous

the 2 is still there |dw:1440867484042:dw|

16. anonymous

now you divide by 2|dw:1440867516200:dw|

17. anonymous

now square both sides to get rid of the exponent|dw:1440867604740:dw|

18. shaniehh

im kinda confuse how would i do that

19. shaniehh

so sorry i suck at math

20. anonymous

square the 1 and square the 2
