Introduction:
The given expression is (Root5 * Root3) / (Root5 - Root3). This can be simplified using rationalization techniques of radicals.

Step 1: Rationalizing the denominator:
To rationalize the denominator, we need to multiply both the numerator and denominator by the conjugate of the denominator, which is (Root5 + Root3).

Thus, we get:

((Root5 * Root3) * (Root5 + Root3)) / ((Root5 - Root3) * (Root5 + Root3))

Simplifying this expression further, we get:

((Root5 * Root3 * Root5) + (Root5 * Root3 * Root3)) / (5 - 3)

Step 2: Simplifying the expression:
The expression can be further simplified by multiplying Root5 with Root5 and Root3 with Root3.

Thus, we get:

(5 * Root3 + 3 * Root5) / 2

Conclusion:
Therefore, the simplified form of the expression (Root5 * Root3) / (Root5 - Root3) is (5 * Root3 + 3 * Root5) / 2.

√5+√3 /√5 -√3 = √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 = 8+2√15 /2
