Prediction is a powerful resource because it can be done in the absence of a compound sample. In mathematics, the binary logarithm (log 2 n) is the power to which the number 2 must be raised to obtain the value n. For example, log 5 1 = 0 since 5 0 = 1. Solution: By using the power rule , Log b M p = P log b M, we can write the given equation as. lg (100) = 2. Exponents and Logarithms work well together because they "undo" each other (so long as the base "a" is the same): They are "Inverse Functions". Tap for more steps p = 7 9 p = 7 9. 2.806+0.
