Question

Value of log(0.02)/(0.07)?

Answer 1

Answer:

Step-by-step explanation:

Well, is it  

log

( 0.02 )( 0.07 )

or  

log ( 0.02 ) 0.07 ? Use your calculator.

log( 0.02 )( 0.07 ) = log( 2 7 ) = log 2 − log 7 = 0.3010 − 0.8451 =− 0.5441 ...

log ( 0.02) 0.07 = log ( 2⋅ 10 − 2 ) 7 ⋅ 10 − 2  = log2− 2 log 10 7 ⋅ 10 − 2 = 100 log 2 − 200 log 107 = 30.10 − 200 7 = 28 7 + 2.10 7 − 210 7+ 10 7 = 4.00 + 0.30− 30.00 + 1.42857  = − 24.27
