What is log base 2?
If a^x = n, where a is a positive real number other than 1 and x is a rational number then logarithm is defined as, logarithm of n to the base a is x. Then is written as log n base a = x.
How do you get 1048576 to the fifth power?
You can do it directly on a calculator and get 1.2676506002282e+30. Or you can use logs like y=n^5 and log y=5*log(1048576)=30.102999566398. Look up the anti-log for the answer.
Why can't you take the log of a negative number?
the log of a number, X, is equal to some value , N, and by definition 10 to the N power =X 10 to any power is always positive
Basic rules to find log and anti log?
no
What is the n power of 2 and get 225?
2n=225 Log 2n=Log 225 (taking logarithm on both sides) n Log 2=Log 225 n=Log 225 / Log 2 n=2.35 / 0.301 n=7.81 (answer rounded to 3 significant figure)
How do you use the anti log on a TI-89 calculator'?
To find anti log of a number enter the number as the exponent of 10.
What is the anti log of 36?
anti-log 36 is base36 Without any qualification "log n" is the "logarithm to any base of n"; though it is often used for common logs, or logs to base 10 (log10 n), which is often abbreviated to lg. On a calculator, the [log] button is used for common logs to base 10, so anti-log 36 = 1036
What is the anti-log of 12.34?
The anti-log of 12.34 is the inverse operation of taking the logarithm of a number. In this case, the anti-log of 12.34 is equal to 10^12.34, which is approximately 2511886431. A logarithm is the power to which a base must be raised to produce a given number, so the anti-log reverses this operation to find the original number.
How do you calculate Log2 in Excel?
Use the LOG function. =LOG(n,b) n = Number b = Base =LOG(2,10) = 0.30103
If a number doubles it is raised to what power?
The answer really depends on what number you are doubling. Let's say that you wish to double the number a (which we assume is greater than 0). If we're raising a to the nth power, then n must satisfy the following equation: an = 2a Taking the natural log on both sides, n log a = log (2a), n = log (2a) / log a. So if we double the number a, it is raised to the log (2a) / log a power.
What is log base 2?
If a^x = n, where a is a positive real number other than 1 and x is a rational number then logarithm is defined as, logarithm of n to the base a is x. Then is written as log n base a = x.

What is the n power of 2 and get 225?
2n=225 Log 2n=Log 225 (taking logarithm on both sides) n Log 2=Log 225 n=Log 225 / Log 2 n=2.35 / 0.301 n=7.81 (answer rounded to 3 significant figure)
What is log 50 to the base 0.1?
log0.1 50 = log10 50 / log10 0.1 ~= -1.699 To work out the log to any base b, logs to another base can be used: When logs are taken of a number to a power, then the power is multiplied by the log of the number, that is: log(bn) = n log b Taking logs to base b the power of b that equals the original number is being found, that is if: bn = m then logb m = n So, by using the logs to a base to which the answer can be known, the log to any base can be calculated: bn = m => n log b = log m => n = log m / log b => logb m = log m / log b as long as the same base is used for the logs on the right. It is normal to use base 10 or base e which are found on calculator buttons marked log (base 10) and ln (log natural - base e).
What is the value of n if 2 to the power of n equals 20000?
2ⁿ = 20000 → log(2ⁿ) = log(20000) → n log(2) = log(20000) → n = log(20000)/log(2) You can use logs to any base you like as long as you use the same base for each log → n ≈ 14.29
