If a, b,c are in G. P., prove that a^n, b^n, c^n are also in G. P.

Step-by-step explanation:

since, a,b,c are in GP.

upon cross multiplying, we get

b² = ac . . . . . (¡)

We have to prove if a^n, b^n and c^n are also in GP.

We'll simply write these numbers in the bove format and if both the sides are equal in the end, it's proved else it's not.

once again cross multiplying

from eqn. (¡) b² = ac

both the sides are equal, sooo our assumption was correct a^n, b^n, c^n are in GP.

don't know sorry bru
