So, does anyone know about rationalizing denominators?
I need help
 What's the square root of 5 over twenty 5 simplified??

sqrt(5) over 25 = 0.0894427191
or 1/11.1803399

You cannot have decimals in fractions. At least, not if you don't want to be yelled at. Just to check, the formula is (5^(1/2))/25? If so, the denominator has already been rationalized. If you want to rationalize the numerator, that's a bit different.

Quote:
Write numerator and denominator in terms of a common base (let's use 5) = 5^(1/2) / 5^2 In division, subtract the exponent in the denominator from the exponent in the numerator = 5^(1/2 - 2) = 5^(-3/2) As John pointed out, this simplification is not an example of rationalizing the denominator, though I see where you might be confused.
