Question

Find the GM of 3 and 27. (Mathematics)​

Answer 1

$Let \: a, b \:and \:c \: are \: in \: G.P$

$\pink { G.M (b) = \sqrt{a\times c}}$

$Here, a = 3 , \: and \: c = 27$

$Geometric \: Mean = \sqrt{ 3 \times 27 } \\= \sqrt{ 3 \times 3\times 3 \times 3 } \\= 3 \times 3 \\= 9$

Therefore.,

$\red{ G.M \: of \: 3 \:and \:27 } \green { = 9 }$
