Question 1091414: given that log7=0.8451and log6=0.7782 find log 25.2 Found 2 solutions by Alan3354, MathLover1:

You can put this solution on YOUR website! 2log (x)=log (25) First use the property of logarithms, , to move the 2 into the argument as an exponent: Now, since the logs of and 25 are equal, they must be equal too: Since this is a quadratic equation, we want one side to be zero. So subtract 25 from each side: Then factor: (x+5) (x-5) = 0 By the Zero …

So we want to expression 12 and 5 as a product, quotient or power of number (s) whose logarithm you were given or whose logarithm you should know. log (12) One way to find this logarithm is as follows: log (12) = log (2*2*3) This expresses 12 as a product of …

You can put this solution on YOUR website! solve for x logx 25 = -2 Use the rule that says: A logarithmic equation of the form logBA = C is equivalent to and can be rewritten as the exponential equation BC = A So we rewrite logx25 = -2 as x-2 = 25 Then we write the x-2 as 1/x2 1/x2 = 25 Multiply both sides by x2: 1 = 25x2 Divide both sides by 25 1/25 = x2 Take positive square roots of both ...

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

In order to use this property the logs have to have coefficients of 1. So we will start by using another property of logarithms: to move the "bad" coefficients into the arguments as exponents: Now we can combine the logs:
