I'll be honest, I don't know if you are right in the beginning. I can, however, tell you how to continue from 4x^2=100, if you are right up until that point. 4x^2=100 Divide both sides by 4. x^2=25 Take the square root of both sides. x=+-5

You have to divide. 3000/270000=90 (because 3/27=9 and you can cancel 3 zeroes from the top and bottom which leaves one zero). 90/63000=700 (9/63=7 cancel 1 zero from the top and bottom and you have 2 zeroes left)
