3log(2^{a} × 3^{b} × 5^{c}) = log(2^{2} × 3^{3} × 5) + log(2^{6} × 3 × 5^{7}) + log(2 × 3^{2} × 5^{4})

We have to find only the value of a

2^{3a} × 3^{3b} × 5^{3c} = (2^{2} × 2^{6} × 2^{1}) × (3^{3} × 3 × 3^{2}) × (5 × 5^{7} × 5^{4})

2^{3a} = 2^{9}

3a = 9

a = 3

The question is **"If log(2 ^{a} × 3^{b} × 5^{c}) is the arithmetic mean of log(2^{2} × 3^{3} × 5), log(2^{6} × 3 × 5^{7}), and log(2 × 3^{2} × 5^{4}), then a equals [TITA]" **
