Geometric mean of 6 and 24 is A) 13 B) 30 C) 12 D) 15

1.	Geometric mean of 6 and 24 is A) 13 B) 30 C) 12 D) 15
Answer» Correct option is (C) 12 Geometric mean of 6 and 24 \(=(ab)^\frac12\) \(=(6\times24)^\frac12\) \(=(2\times3\times2\times4\times3)^\frac12\) \(=(2^2\times2^2\times3^2)^\frac12\) \(=(12^2)^\frac12\) = 12 Hence, geometric mean of 6 and 24 is 12. Correct option is C) 12 correct answer is option c)12

Answer»

Correct option is (C) 12

Geometric mean of 6 and 24 \(=(ab)^\frac12\)

\(=(6\times24)^\frac12\)

\(=(2\times3\times2\times4\times3)^\frac12\)

\(=(2^2\times2^2\times3^2)^\frac12\)

\(=(12^2)^\frac12\) = 12

Hence, geometric mean of 6 and 24 is 12.

Correct option is C) 12

correct answer is option c)12
