Question

The mean proportion between √√26-√17 and √26+√17 is​

Answer 1

Answer:

3

Step-by-step explanation:

Given two numbers are (√26 - √17) and (√26 + √17)

Here

a = √26 - √17

b = √26 + √17

We know that mean proportion(say G) of two numbers are given by

G = √ab

G² = ab

G² =(√26 - √17)(√26 + √17)

G² = (√26)²-(√17)²

G² = 26 - 17

G² = 9

G = √9

G = 3

Thus mean proportion of given two

numbers is 3

(73) A. - 069

Note:- We have used the following formulas in the solution

1. (a + b)(a - b) = a² - b²

2. (√x)² = x
