WitrynaWhen "log" is written without subscripts (little numbers below the word log) it is assumed to be base 10. The 10 is left out. (Like the positive sign in positive numbers). So here you are adding two logarithms with base 10. As Sal explains log (a)+log (b) = log (a times b). The answer here is log (15). ( 2 votes) Show more... Alex 12 years ago WitrynaSquaring a number is the same as raising that number to the power of two. The square function (ƒ (x)=x 2) is the inverse of the square root function (ƒ (x)=√x). Raising a number n to the power of 2 is called “squaring” because the resulting number n2 corresponds to the area of a square with sides of length n.

Witryna(Root) Mean Squared Log Error: M S L E = m e a n ( ( l o g ( p + 1) − l o g ( y + 1)) 2) . In [0,∞), the smaller the better. This is useful when dealing with right skewed targets, since taking the log transform makes the target more normally distributed. WitrynaOur first attempt got us from 4 to 3.25. Going again ( b to e) gets us: 3.163. Going again ( b to e) gets us: 3.1623. And so, after 3 times around the answer is 3.1623, which is pretty good, because:

WitrynaAll the imaginary numbers can be written as a+ib where a is the real part and b the imaginary. Let us assume that i^1/2 = a+ib for some a and b. i= (a+ib)^2 i=a^2 + ib^2 + 2aib ib^2 = -b^2 i=a^2-b^2+2aib As the left hand side has only imaginary part, a^2 - b^2 =0 a=b (taking principal roots) so, i = 2aib 2ab = 1 2a^2 = 1 (a=b) a=1/√2 b=1/√2 WitrynaStep 1: Enter the radical expression below for which you want to calculate the square root.
