What is log 50 to 3 decimal places? - Socratic
log 50 ~~ 1.699 Note that 50 = 100/2 So: log 50 = log (100/2) = log 100 - log 2 ~~ 2-0.301 = 1.699 Note that a very good approximation for log 2 which is worth remembering is 0.30103. The actual value of log 2 is closer to 0.30102999566398, so you actually get 8 significant figure accuracy for the sake of remembering 5 digits.
How do you calculate log50 with a calculator? - Socratic
2016年10月2日 · You will need a scientific calculator. They work in different ways ... Some you key in 50 first, then press the log key. The answer appears on the display immediately (These are generally the older models) Others work with D.A.L. (direct algebraic logic). Press the log key then 50 and then =. You should get the answer as 1.69897...

2016年6月8日 · In fact one need to remember log (to the base #10#) for first ten numbers and it makes things lot easier. Note that while #log1=0# , #log10=1# . In fact, you just need to know #log2=0.3010# , #log3=0.4771# and #log7=0.8451# and …
How do you solve 2 log x = log 25 - Socratic
2015年12月29日 · Use the fact that log(x) is a one-one function as a Real-valued function of Real numbers to find: x = 50 Divide both sides by 2 to get: log(x) = (log(25)+2) / 2 = (2 log(5) + 2 log(10))/2 = log(5) + log(10) = log(50) Hence x = 50, since log(x):(0, oo) -> RR is one-one.

How do you approximate log_5 50 given log_5 2=0.4307 and log …
2016年12月21日 · log_5 50 ~= 2.4307 log_5 50 can be written as log_ 5 (2 xx 25), which can be rewritten as log_a(n xxm) = log_a n + log_a m. => log_5 2 + log_5 25 We know the value of log_5 2 is 0.4307 but to find the value of log_5 25 we must use the change of base rule such that log_a n =logn/loga. => 0.4307 + log25/log5 Rewrite 25 and 5 in powers of 5. => 0.4307 + log(5^2)/log(5^1) We now use the power rule ...
