Question

if a b c are in G. P then AC=​

Answer 1

Answer:

Correct option is

A

ac=b

2

a,b,c are in GP

⟹r=

a

b

=

b

c

⟹b

2

=ac

Answer 2

c [a² + b²]

Step-by-step explanation:

since a , b , c are in GP

b²= ac .. ( i )

a( b²+ c² ) = a ( ac + c²)

= a²c + ac ²

= c[ a²+ ac ]

= c[ a² + b² ]
