How to solve for exponent variables
Did you know?
WebBy taking the log of an exponential, we can then move the variable (being in the exponent that's now inside a log) out in front, as a multiplier on the log. In other words, the log rule … WebAfter this step, we can apply the quotient property of exponents and solve the variable, that is, a 7 /a 2 = a 7 - 2 = a 5. So, now we have the coefficient as 3 and the variable is a 5. ... Variable as the Exponent. Let us see how to use the rules when the exponent is a variable. For example, solve: 5 ...
WebYou can't carry over a base and use the exponentiation symbol multiple times. Think of it like eating a banana. Your banana is gone after the operation; you'll need to get another one … WebSteps to Solve Exponential Equations using Logarithms 1) Keep the exponential expression by itself on one side of the equation. 2) Get the logarithms of both sides of the equation. You can use any bases for logs. 3) Solve for the variable. Keep the answer exact or give decimal approximations.

WebDec 15, 2016 · To solve your equation, take the base-2 logarithm of both sides: log 2 2 4 x + 1 = log 2 128 4 x + 1 = 7 x = 1.5 However, is there a way of solving this without knowing that 128 = 2 7? Well, this piece of information is equivalent to “knowing that log 2 128 = 7 ”, so no.
