Applying cross multiplication, it is found that the value of x is given by:
\(x = \pm \sqrt{ab}\)
What is the expression?
The expression is given by:
\(\frac{a}{x} = \frac{x}{b}\)
Applying cross multiplication, we have that the first step towards finding the solution for x is given as follows.
\(x^2 = ab\)
Considering that when the square root is removed, we have to remember the plus/minus sign:
\(x = \pm \sqrt{ab}\)
Which is the desired value of x.
