Question

If a/b=b/c,then what is b²?​

Answer 1

Given:

The equation is

$\dfrac{a}{b}=\dfrac{b}{c}$

To find:

The value of $b^2$.

Solution:

We have,

$\dfrac{a}{b}=\dfrac{b}{c}$

On cross multiplication, we get

$a\times c=b\times b$

$ac=b^2$

$b^2=ac$

Therefore, the value of $b^2$ is $ac$.
