Question

if x is the geometric mean of 16 and 9 than find the value of x

Answer 1

16:x::x:9
We know that product of means is eaqual to the product of extremes
x*x=16*9
x2=144
x=12

Answer 2

Hi , Geometric mean of number given by formula = √ ab


x = √ 16× 9

=> 12

hence , the value of x is => 12

hope it help you !!

thanks !!
