How solve this math problem root5 +root3/root5-root3 of root 15=3.387?

Answer 1

Given,

√5+√3/√5-√3×√5+√3/√5+√3

Calculation,

=√5+√3/√5-√3×√5+√3/√5+√3

=(√5+√3)²/(√5)²-(√3)²

=(√5)² + (√3)² + 2×√5×√3/ 5-3

=5+3+2×√15/2

Putting the value of √15 which is 3.387

So, we get

=8+2×3.387/2

=8+1×3.387

=8+3.387
