                       log(4)  +  log(2)  -  log(5)

                 =    log(2²) +  log(2)  -  log(5)

                 =    2 log(2) + log(2)  -  log(5)

                 =      3 log(2)  -  log(5)

                 =      log(2³)  -  log(5)

                 =        log (2³/5)

                 =        log (8/5)

                 =        log (1.6)  =  0.2041...  (rounded)

PLEASE HELP {It costs 5,700 every one sixth of an hour to build a hotel how many cents does building a hotel cost per second?}
Keith_Richards [23]
One sixth of an hour is 10 minutes.
That means it costs 5,700 every 10 minutes.

Costs 5,700 = 10 minutes

Dive 10 on both sides.

Costs 570 = 1 minute

Lets convert the minute into seconds.

Costs 570 = 60 seconds

Divide both sides by 60.

Costs 9.5 cents = 1 second

Round it off since you can't pay 9.5 cents.

Costs 10 cents = 1 second

This means that every second they pay 10 cents for the hotel. :D

How to find square root ?​
Dominik [7]

To estimate a square root, find the two perfect squares the number is closest to, then continue with further decimals, i.e. if the question is square root of 5, it is between 4 and 9.  As such, the answer is between 2 and 3.  Alternatively, use a calculator for a quick estimation of many decimal points.
