Answer:
Step-by-step explanation:
From the way it is written, the 
is outside the square root. I will rewrite it as:
Multiply denominator and numerator by 3
Factor 
Divide denominator and numerator by
Let's rewrite it again
It is already in the form 
Expanding the perfect square, we have
Factor 
Therefore,
Answer:
x = 49
Step-by-step explanation:
This is an inverse relationship and it implies that, an increase in the value of one variable results in a subsequent decrease in the value of another variable.
Given the mathematical expression and data;
y = 1/√x
y = 7 and x = 64
First of all, we would find the constant of proportionality, k;
y = k/√x
7 = k/√64
7 = k/8
k = 7 * 8
Constant, k = 56
Now, to find the value of x when y = 8
y = k/√x
Substituting the values, we have;
8 = 56/√x
Cross-multiplying, we have;
8 * √x = 56
√x = 56/8
√x = 7
Taking the square of both sides, we have;
(√x)² = 7²
x = 49
