You can put this solution on YOUR website!
something%2Asomething=50, both "something" must be the same.

sqrt%2850%29sqrt%2850%29=50

You should know from basic multiplication facts that 50 is near 49, and sqrt%2849%29=7. You should expect that sqrt(50) is larger than 7 but much less than 8.

sqrt%2850%29
sqrt%285%2A2%2A5%29
sqrt%285%2A5%2A2%29
sqrt%285%29sqrt%285%29sqrt%282%29
5sqrt%282%29

If you'all know how to find an approximation for square root of two, then you can just perform the multiplication.
1.4142 is APPROXIMATELY square root of 2.
