[SQRT(4)*SQRT(3)] * [SQRT(5) * SQRT(2)] =
2 * SQRT(3) * SQRT(5) * SQRT(2)
It is common to reduce large numbers under the radical to a string of factors having prime numbers under the radicals.
Square root of 217 for apex
Irrational.
The square root of a negative number cannot be expressed with integers. The square root of a negative number is always imaginary.
The 8th root

Square root of 217 for apex
One way is trial and error. The square root of 121 is 11. So the square root of 120 is just under that. 10.9 squared is 118.81 10.95 squared is 119.9. 10.954 squared is 119.99 which is close enough for me.
12
The answer, assuming that 120 is degrees and not radian is -square root of 3.
sqrt(120)
10.9545
120The answer is 120.
10.954i
No, it is not. For it to be a perfect square, the square root of it would have to be an integer, but √120 ≈ 10.954. 100 and 121 are perfect squares nearest to 120. ■
Irrational.
square root of (6 x 20) = square root of (120) = 10.95
