Math HELP please
the square root of 24? okay, find two factors of 24, like 6 and 4. six hads no square root so it stays in the radical, and the square root of 4 is two, so it goes outside the radical. so the answer is 2times the square root of 6.

How do you work square root problems when there is a number outside the radical that needs to be divided out. Example: 2(square root of 5x-1)=3(square root of 2x+4). How can you get both of the radicals by themselves in order to solve the equation?

If you have a scientific calculator, you can make the caculation then round the number. The square root of 42 is between 6 (which is the square root of 36) and 7 (which is the square root of 49). The actual calculation is 6.4807406. Rounded to the nearest tenth is 6.5
