Find the value of a if 3 minus under root 5 upon 3 2 under root 5 is...
Solution:

Given: 3 - sqrt(5)/3 * 2sqrt(5) = a * sqrt(5) - 19/11

To Find: Value of a

Step 1: Simplify the left-hand side of the equation

We know that 3 - sqrt(5) = (3sqrt(5) - sqrt(5)^2)/3 = (3sqrt(5) - 5)/3

Therefore, 3 - sqrt(5)/3 * 2sqrt(5) = (3sqrt(5) - 5)/3 * 2sqrt(5)/3 = (6sqrt(5) - 10)/9

So, our equation becomes:

(6sqrt(5) - 10)/9 = a * sqrt(5) - 19/11

Step 2: Multiply both sides by 99 to eliminate the denominators

99 * (6sqrt(5) - 10)/9 = 99 * (a * sqrt(5) - 19/11)

Simplifying this equation, we get:

22(6sqrt(5) - 10) = 9a * sqrt(5) * 99 - 19 * 99

Step 3: Solve for a

Expanding the left-hand side of the equation, we get:

132sqrt(5) - 220 = 891a * sqrt(5) - 1881

Grouping the terms with sqrt(5), we get:

(132 - 891a) * sqrt(5) = 1699

Dividing both sides by sqrt(5), we get:

132 - 891a = 1699/sqrt(5)

Solving for a, we get:

a = (132 - 1699/sqrt(5))/891

Simplifying, we get:

a = (132sqrt(5) - 1699)/4455

Therefore, the value of a is (132sqrt(5) - 1699)/4455.
