we \: know \: that \\  \\  log_{}(x {}^{n} )  = n log(x)  \\  \\ and \\  \\  log(mn) =  log(m)  +  log(n)  \\  \\  \\  \\  \\  log((27x) {}^{1 \div 2} \div x {}^{3}  )  \\  \\  \\  log(3 {}^{3 \div 2} \times x {}^{1 \div 2}  \div x {}^{3}  )  \\  \\  \\  log(3 {}^{3 \div 2}  \times x {}^{ - 5 \div 2} )  \\  \\  \\  log( {3}^{3 \div 2} )  +  log(x {}^{ - 5 \div 2} )  \\  \\ (3 \div 2) log(3)  -(5 \div 2) log(x)  \\  \\  \\ (1 \div 2)(3 log(3)  - 5 log(x)


hariharan108: How x power -5/2 came
Anonymous: x½-³ = x ^ ( 1 -6 )/5 = x^ ( -5/6)
Anonymous: sorry x ^ ( -5/2)
Anonymous: x^ ( 1/2 - 3 ) = x^( 1-6)/2 = x^ ( -5/2)
