There are rules when performing operations involving exponents of the same base. Only the coefficients of the terms with the same exponents and base are added and subtracted. When multiplying terms with the same base, the product has the same base and the sum of the exponents. When dividing,...
or powers, with the same base. The quotient rule says that when you are dividing x^m by x^n, you can simply subtract the two exponents (m-n) and keep the same base. You must always subtract the denominator from the numerator for the quotient rule to work, and x cannot equal...
We can simply multiply the powers and keep the base the same. What is Power of a Power Rule for Negative Exponents? When the power of the base is negative, we can apply the same formula (am)n = amn by multiplying the exponents. If m > 0 and n > 0, then we have (a-m)-n =...
LL0N (or LL/N) and LLN log-log folded e − x {\displaystyle e^{-x}} and e x {\displaystyle e^{x}} scales, for working with logarithms of any base and arbitrary exponents. 4, 6, or 8 scales of this type are commonly seen. Ln linear scale used along with the C and D ...
We see that we are multiplying by the reciprocal of five a total of five times: x−2×x−3=(1x)5 This is the same thing as raising the base number five to the negative fifth power: x−2×x−3=x−5 The pattern here is that the exponent on the product is the sum of ...
natural log is the time for e^x to reach the next value (x units/sec means 1/x to the next value) With practice, ideas start clicking. Don't worry about getting tripped up -- I still tried to overuse the chain-rule when working with exponents. Learning is a process!

Logarithms of the latter sort (that is, logarithms with base 10) are called common, or Briggsian, logarithms and are written simply log n. Invented in the 17th century to speed up calculations, logarithms vastly reduced the time required for multiplying numbers with many digits. They were ...
