√3 x √21 = √3 x √(3 x 7) = (√3 x √3) x √7) = 3√7
The square root of 12 may be simplified to 2 times the square root of 3.
12 times 5 is 60
sqrt(3) x sqrt(15) = sqrt( 3 x 15 ) = sqrt( 45 ) = sqrt( 9 x 5 ) = 3 sqrt(5)
It is: 12 times sq rt of 6
12 radical 6 x 6 radical 6 = 72 x 6 = 432
"Radical x times radical x" could be interpreted as the square root of x times the square root of x - in which case the product would be x (the number under the radical sign)
x√x=x^1.5
12 radical 2 you multiply 6 and 2 :)
√3 x √21 = √3 x √(3 x 7) = (√3 x √3) x √7) = 3√7
√2 x √2 = (√2)2 = 2
The square root of 12 may be simplified to 2 times the square root of 3.
3 sqrt(6) x sqrt(6) = 18
12 x 12 x 12 x 12 x 12 = 125 = 248,832
Radical (3x) = radical(x) * radical(3).
Because the radical cancels out the "x".
12 x 12 x 12 x 12 x 12
