Question

What is √28 in simple radical form

Answer 1

Answer would be √28=2√7.

Answer 2

To simplify a radical, first we find numbers that multiply by each other to get the given number (in this case, 28) while having one of the numbers as a number that has a square root.

We see that 7*4 equals 28, and 4  is a number that has a square root, so we'll do:
$\sqrt{4*7}$
Which is $2 \sqrt{7}$ (because we found the square rot of 4 to be 2, therefore the two get moved outside the radical).
