log5 x = 3 we do not want the log bit, so we need to remove it. We remove anything in maths by doing the opposite. The opposite of log5 is to raise to base 5: log5 x = 3 becomes 5^log5 x = 5^3 and the "5^log5" cancels each other out. That is the …

We rejected it because the logarithm arguments became negative when x was that we rejected it. In other problems it might work out that a negative value for x would be OK but a positive one would not. And sometimes both answers check and sometimes no answers work.)

We now have an equation without logs and where the variable is "out in the open". Now we use algebra to solve for x. Let's start by getting rid of the fraction. Multiplying both sides by (x-4) we get: 25x - 100 = x - 2 Subtracting x from both sides: 24x - 100 = -2 Adding 100 to each side: 24x = 98 Dividing by 24 we get:

Question 624523: solve the equation 9 log5 x = 25 logx 5, expressing your answers in the form 5^p/q, where p, and q are integers Found 2 solutions by Alan3354, Theo : Answer by Alan3354(69443) ( Show Source ):

x-7 = 25 This is a very simple equation to solve for x. Just add 7 to rach side: x = 32 When solving logarithmic equations it is important, not just a good idea, to check your answer. You must ensure that no arguments (or bases) of any logarithm become zero or negative. And when checking we should use the original equation: Checking x = 32:

Without using a calculator, evaluate log5(125).. log5(125)=x convert to exponential form The base raised to the logarithm of the number is equal to the number. logarithm of the number=x, base=5, and the number=125 5^x=125 5^x=5^3 exponents …

You can put this solution on YOUR website! log 5 25 = x is explained in exponential form. 5 ^ x = 25 Therefore, x is 2.
