Question

Four geometric means are inserted between the

numbers 211 – 1 and 211 + 1. The product of these

geometric means is​

Answer 1

2. $211 {}^{2} - 1 {}^{2}$

Answer 2

Answer:

• given : (6-4√3) / (6+4√3) = a√3+b
• now simplify this

(6-4√3) / (6+4√3)

= (6-4√3)^2 /6^2- (4√3)^2

= (36+48-48√3)/36-48

= (84-48√3)/(-12)

= 4√3 - 7

we know that it is equals to a√3+b

so we can claim that a=4. b=-7

now a+b = -3
