Rationalizing and Evaluating 6/√(5)√(3)
Step 1: Rationalizing the Denominator
In order to rationalize the denominator, we need to multiply both the numerator and denominator by the conjugate of the denominator. The conjugate of √(5)√(3) is √(5)√(3), which means we need to multiply the expression by (√(5)√(3))/(√(5)√(3)).
Thus, we have:
6/√(5)√(3) x (√(5)√(3))/(√(5)√(3))
Simplifying the numerator and denominator, we get:
6√(15)/15
Step 2: Evaluating the Expression
Now that we have rationalized the denominator, we can evaluate the expression using the given values of √(5) and √(3).
Substituting √(5) = 2.236 and √(3) = 1.732, we get:
6√(15)/15 = 6(2.236)(1.732)/15
Simplifying the expression, we get:
6√(15)/15 ≈ 2.776
Conclusion
The value of 6/√(5)√(3) when √(5) = 2.236 and √(3) = 1.732 is approximately 2.776. Rationalizing the denominator involved multiplying both the numerator and denominator by the conjugate of the denominator, while evaluating the expression involved substituting the given values of √(5) and √(3) and simplifying the expression.
