3 radical 5
You probably mean what is the simplest form of sqrt 45....? 45=3x3x5 3x3 is a square number, so sqrt45=sqrt(9*5)=sqrt(9)*sqrt(5)=3*sqrt(5) * indicates multiplication sqrt indicates a square root (also known as a surd (in the english national curriculum) or a radical...apparently
sqrt(3) x sqrt(15) = sqrt( 3 x 15 ) = sqrt( 45 ) = sqrt( 9 x 5 ) = 3 sqrt(5)
There is no reasonable radical approximation for radical 11.
Not necessarily. If it is the same radical number, then the signs cancel out. Radical 5 times radical 5 equals 5. But if they are different, then you multiply the numbers and leave them under the radical sign. Example: radical 5 * radical 6 = radical 30
3 radical 5
45+45+90
This would be pi/4 radians or 45 degrees.
5sqrt(81) is the same as saying ..... 5 * 9 = 45
sqrt(45) = sqrt(9 x 5) = 3 sqrt(5)

45 is 9 times 5, and 9 is 3 squared, so the answer is 9 times the square root of 5.
sqrt(3) x sqrt(15) = sqrt( 3 x 15 ) = sqrt( 45 ) = sqrt( 9 x 5 ) = 3 sqrt(5)
A radical is a root.A radical is a root.A radical is a root.A radical is a root.

Here is an example, radical 20 plus radical 5. Now radical 20 is 2(radical 5) so we can add radical 5 and 2 radical 5 and we have 3 radical 5.
Radical (3x) = radical(x) * radical(3).
