How do you find the square roots of fractions?

Question

I need to know

Answer 1

convert them into decimals and the take a square root

i'd recommend use a calculator :P

Answer 2

Square root is a fractional exponent. For example, sqrt2 = 2^ (1/2)

An exponent applied to a fraction is evaluated by raising both numerator and denominator to that exponent,
ex: (2/3)^2 = (2^2) / (3^2) = 4 / 9

So since square root is an exponent, you do the same thing, take the square root of numerator and denominator

sqrt(25/16) = (25/16) ^ 1/2 = (25 ^ 1/2) / (16 ^ 1/2) = 5 / 4

Answer 3

Convert fraction to decimal,get the square root of the decimal.

Answer 4

You can find the square root of the numerator, the square root of the denominator, and then divide. Or, if you have numbers, do the division on your pocket calculator and press the square root key.

Answer 5

A gentleman already answered correctly.., convert to decimal function then find the square root

Answer 6

Using Scientific Calculator...

Answer 7

Take the sq rt of Numerator then divide by the sq rt of denominator

Answer 8

Example:

sqrt(1/4) = sqrt(1) / sqrt(4) = 1 / 2

Another:

sqrt(7/8) = sqrt(7) / sqrt(8)
=sqrt(7) / [sqrt(2)*sqrt(4)]
=sqrt(7) / 2*sqrt(2)
=[sqrt(7)*sqrt(2)] / [2*sqrt(2)*sqrt(2)] --->rationalize the denominator, to get rid of "sqrt" in denominator.
=sqrt(14) / 2*2
=sqrt(14) / 4

Answer 9

sqrt(a/b) = (sqrt(a))/(sqrt(b)) = (sqrt(ab))/b

sometimes its easier if you can just go ahead and sqrt the denominator, but if you can't then just use the formula above.

Answer 10

at least give me one example.
