Question

How do you change a number into a radical?
Example: Square root of 24.

Answer 1

You factor 24 into 2 #s that when multiplied, give you 24. One of them has to be a perfect square. For 24, the 2 #s are 4 and 6.\[\sqrt {24} = \sqrt {4 *6} = \sqrt {4} * \sqrt {6} = 2 \sqrt {6}\]

Answer 2

Thank you so much!

Answer 3

No problem, just try a few problems on your own and you should get the hang of it :)
