sqrt%2820%29%2Asqrt%2810%29+=+sqrt%2820%2A10%29
sqrt%2820%2A10%29+=+sqrt%28200%29
sqrt%28200%29+=+sqrt%28100%29%2Asqrt%282%29
sqrt%28100%29%2Asqrt%282%29+=+10%2Asqrt%282%29 answer
Note that 100 is the largest perfect square
that can be factored out o 200

-----------------
You can do that, but I'd go this way:
sqrt%2820%29%2A+sqrt%2810%29+=+sqrt%28200%29
= sqrt%28100%29%2Asqrt%282%29
= 10sqrt%282%29
