If x = 7 4 root 3 and xy = 1 then find one upon X square 1 upon y square?
Most Upvoted Answer
If x = 7 4 root 3 and xy = 1 then find one upon X square 1 upon y ...
Given:
To find:
- x = 7√3
- xy = 1
To find:
- 1/x² + 1/y²
Solution:
Let's first find the value of y.
Given, xy = 1
Therefore, y = 1/x
Now, substituting the value of x and y in the expression 1/x² + 1/y², we get:
1/x² + 1/y² = (1/(7√3)²) + 1/(1/x)²
1/x² + 1/y² = (1/147) + x²
Now, we need to find the value of x².
Given, x = 7√3
Therefore, x² = (7√3)² = 147
Substituting the value of x² in the expression 1/x² + 1/y², we get:
1/x² + 1/y² = (1/147) + 147
1/x² + 1/y² = (1/147) + (147/1)
1/x² + 1/y² = 148/147
Answer:
1/x² + 1/y² = 148/147
