Question

10 + squareroot 10m-1=13

Answer 1

any choices

Answer 2

3 = sqrt(10m - 1)
9 = 10m -1
10 = 10m
1 = m

Answer 3

I think the question needs to more clear: is it 10+SQRT(10m-1)=13 or 10 + SQRT(10m) -1=13?

Answer 4

it's obviously sqrt(10m-1) not sqrt(10m) -1 since the latter would result in a very strange... uhmm... result >.>

Answer 5

@snuggles7 haha true but I have seen stranger questions n answers before!
Back to the question, first thing is to subtract 10 on both side of =. then square to get rid of SQRT...
