where there is no base then we consider it with base 10 eg - log₁₀2
3log5 + 6log2 - 2log10
= log 5³ + log 2⁶ - log 10²
=
= log 10 x 2³
= 1 + 3log 2 {log 2 = 0.301}
=1.90 ANSWER

given 3log5+6log2-2log10
there is no base so consider it as 10
3log₁₀5+6log₁₀2-2log₁₀10 = log₁₀5³+log₁₀2⁶-log₁₀10²
= log₁₀390625+log₁₀64/log₁₀10²
= log₁₀ ( 390625×64)/log₁₀10²
= log₁₀(25000000)/log₁₀100
= log₁₀(25000000/100)
= log₁₀ (250000)
= log₁₀25×10000
= log₁₀25×10⁴
= log₁₀5²+log₁₀10⁴
= 2log₁₀5+4log₁₀10
= 2log₁₀5+4
= 2(log₁₀5+2)
=2(0.699+2)
= 2(2.699)
= 5.398
