Write and then evaluate a subtraction expression to determine the overall change in how do you write log2 (1/8) = -3 in exponential form? the 1/8 is a fraction and the 2 is a base of 2. thanks jaime. Jamie, For any positive number a, 2 log 2 (a) = a. Thus in your equation if you raise both sides to the power of 2 you get. 2 log 2 (1/8) = 2-3 o Similarly, a change from 30 to 15 is referred to as a 2-fold decrease.In genomics, log ratios are often used for analysis and visualization of fold changes. The log2 (log with base 2) is most commonly used. For example, on a plot axis showing log2-fold-changes, an 8-fold increase will be displayed at an axis value of 3 (since 2^3 = 8)

  1. by log2^2 i mean that the base of the log is 2. All of the bases are 2, and then it goes up log2, log4,log8 log2^n. That's all it says. I think the answer has to be a single number. Maybe number 2
  2. For instance, the values for 2,3,4,5,6,7,8 are 1,2,2,3,3,3,3 .

So we could say 8 to some power-- and that exponent that I'm raising 8 to is essentially what this logarithm would evaluate to. 8 to some power is going to be equal to 2. Well, if 2 to the third power is 8, 8 to the one-third power is equal to 2. So x is equal to 1/3. 8 to the one-third power is equal to 2, or you could say the cube root of 8 is 2 log2: Chrome 完全対応 38: Edge 完全対応 12: Firefox 完全対応 25: IE 未対応 なし: Opera 完全対応 25: Safari 完全対応 8: WebView Android 完全対応 38: Chrome Android 完全対応 38: Firefox Android 完全対応 25: Opera Android 完全対応 25: Safari iOS 完全対応 8: Samsung Internet Android 完全対応 3.0. log2. Return 2-based logarithm. Declaration. Source position: math.pp line 34 To evaluate $\log_8 128$, let $$\log_8 128 = x$$ Then by definition of the logarithm, $$8^x = 128$$ Since $8 = 2^3$ and $128 = 2^7$, we obtain \begin{align*} (2^3)^x & = 2^7\\ 2^{3x} & = 2^7 \end{align*} If two exponentials with the same base are equal, then their exponents must be equal Now remember, log 2 x = 4/3 means the power that you raise 2 to in order to get x is 4/3, so x = the cube root of 2 4
