2+log x=log 45-log 2+ log 16-2 log 3
2+log x = log 45/2 x 16/3 to the power 2
2+log x = log 45/2 x 16/3*3
2+log x = log 45/2 x 16/9
2+log x = log 5 x 4
2=log 20 - log x
2 = log 20/x
10 to the power 2 =20/x
x = 20/100
x= 0.2

But in my text book answer is 0.40
check with your Math teacher maybe sometimes textbook answers will be printed wrong
OK it's fine but how log 5*4 are u getting
by cancelling (log 45/2 x 16/9) we get (45/2 = 5) and (16/9 = 4)
