15 radical 2
Quadrilateral
18 multiplied by 5 is 90.
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
18/5 or 3.6

5sqet(2) + sqrt(18) NB sqrt(18) = sqrt(2 x 9) = sqrt(2)Sqrt(9) = 3sqrt(2) Hence 5 sqrt(2) + 3sqrt(2) = 8sqrt(2)
1 squared radical 40 is equal to 1 squared radical (4 x 10), and this become 2 squared radical 10. By adding 2 squared radical10 with 3 squared radical 10 we get 5 squared radical 10.
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.
18 multiplied by 5 is 90.
