Question

find the mean propotional between 16 and 25,64 and 81​

Answer 1

Answer:

i) 16 and 25...

let mean proportional be x

Then, x*x=16×25

x²=400

x=√400=20

So, the mean proportional is 20

ii) 64 and 81

let mean proportional be x

Then, x*x=64×81

x²=5184

X=√5184=72

So,the mean proportional is 72
