Undoing an exponent

WebAddition and multiplication are commutative, so there is just one inverse function. Exponents are not commutative; 2 8 ≠ 8 2. So we need two different inverse functions. Given b e = r, we have the " n th root" operation, b = r e. It turns out that this can actually be written as an exponent itself: r e = r 1 / e. WebIf you take the log of a number, you're undoing the exponent. The key difference between natural logs and other logarithms is the base being used. Logarithms typically use a base of 10 (although it can be a different value, …

WebAdding exponents is the process of adding exponents or powers of a number irrespective of the base being the same or not. Exponents can also be called the power of the numbers as it represents the number of times a number is multiplied by itself. For example, 3 2 = 3 × 3, where 3 is the base and 2 is the exponent.. Here, in the term x n,. x is called the base WebThe backwards (technically, the "inverse") of exponentials are logarithms, so I'll need to undo the exponent by taking the log of both sides of the equation. This is useful to me because …

WebThe negative sign on an exponent means the reciprocal. Think of it this way: just as a positive exponent means repeated multiplication by the base, a negative exponent means repeated division by the base. So 2^ (-4) = 1/ (2^4) = 1/ (2*2*2*2) = 1/16. The answer is 1/16.
