No, the statement -- as you show it -- is not true.

sqrt%288%29%2B2sqrt%2815%29 is not equal to sqrt%283%29%2Bsqrt%285%29.

Don't use the "√" symbol in writing your expressions or equations; or, if you do, use parentheses appropriately.

This statement IS true:

sqrt%288%2B2sqrt%2815%29%29+=+sqrt%283%29%2Bsqrt%285%29

...or, using your notation and appropriate parentheses....

√(8+2√15)=√3+√5 TRUE
