radical 15 cannot be simplified.
√15
Since 60 can be factored to 4 times 15, then radical 60 equals 2 times radical 15.
When multiplying two square roots together, it is helpful to remember the following rule: root ab = (root a)(root b) In this case we can multiply 10 by 15 to get 150, and say the answer is the square root of 150. This can then be split up again into root 25 and root 6. Root 25 = 5, so the simplest form of the answer is "5 root 6" This is approximately 12.247

The square root of 225 is 15.
Yes, the square root of 225 is ± 15 because 15 x 15 = 225 AND -15 x -15 = 225

The square root of 15 is simply root 15, since neither 3 nor 5, 15's only factors, have square roots.
Since 60 can be factored to 4 times 15, then radical 60 equals 2 times radical 15.
sqrt(135) = sqrt(9*15) = sqrt(9)*sqrt(15) = 3*sqrt(15)

The square root of 60 is the square root of 2 x 2 x 3 x 5. When that is simplified, a 2 comes out from under the radical sign, resulting in a final answer of 2 radical 15.
3√250 = 15√10 The cube root of 250 is 5 times the cube root of 2.
If we factor 60, we get 60 = 2 * 2 * 3 * 5 So sqrt ( 60 ) = sqrt (2 * 2 * 3 * 5) = sqrt (2 * 2) * sqrt (3 * 5) = 4 * sqrt( 15 ) ____________________________________________________________ actually if you do by just using the simpler way you should get 2 radical 15 since , 60 has the closest perfect square of 4 and non perfect of 15 this is how you should solve radical 60 = radical 4 times radical 15 radical 60 = simplify the 4 to 2 and leave radical 15 So , radical 60 = 2 radical 15 not what is above .
