I also need help getting the formula to solve a question:
(I have already arrived at an answer, but I used logic and not a formula to get to it)
One eighth of the square root of 7 less than a number is 2 what is the number?
my answer:
263
I got to that answer by saying that if 2 was one eighth the square root of the number, minus seven, then 16=the square root and since 16^2=256 then the number must be 256+7=263
Thank you again for your help!
