There is no answer - it is an error: negative numbers do not have logarithms.

The log if a number tells to what power the (positive) base must be raised to get the number. Raising any positive number to any power will never result in a negative number, so it is an error to try and take the log of a negative number.

log(9x) + log(x) = 4log(10)log(9) + log(x) + log(x) = 4log(10)2log(x) = 4log(10) - log(9)log(x2) = log(104) - log(9)log(x2) = log(104/9)x2 = 104/9x = 102/3x = 33 and 1/3


How do you solve logx minus 3 plus log 4 equals log x?

Use the identity log(ab) = log a + log b to combine the logarithms on the left side into a single term. Then take antilogarithms (just take the log away) on both sides.

What is 15log2.5x equals 100?

It's a logarithmic equation in one unknown.If you'd like to know the value of 'x' that makes it true, you can find it like this:15 log(2.5x) = 100log(2.5x) = 100/15 = 20/3log(2.5) + log(x) = 20/30.39794 + log(x) = 20/3log(x) = 20/3 - 0.39794x = 1020/3 / 100.39794x = 1,856,635.533=============================Check:log(2.5 x 1,856,635.533) = 20/315 (20/3) = 300/3 = 100 yay!

2log 4y equals log 7 343 - log 5 25?

2 log(4y) = log7(343) - log5(25)log7(343) = 3log5(25) = 22 log(4y) = 3 - 2 = 1log(4y) = 0.54y = sqrt(10)y = 0.25 sqrt(10)y = 0.79057 (rounded)


How would you rearrange the equation 4 equals 2 over 3 log x minus 0.9 to find x?

Without brackets, there are many ambiguities in the question. 4 = 2/3*log(x) - 0.9 4.9*3/2 = logx 7.35 = logx so x = 107.35 However, the original equation could also have referred to 4 = 2/3*log(x-0.9) or 4 = 2/[3*log(x)] - 0.9 or 4 = 2/[3*log(x-0.9)]


Given log 2 and log 3 how do you compute log 36?

log(36) = 1.5563To solve this problem without using a scientific calculator, factor 36 into 2*2*3*3, and use the formula:log(a*b) = log(a) + log(b)So, in this case:log(36) = log(2) + log(2) + log(3) + log(3) = 0.3010 + 0.3010 + 0.4772 + 0.4772 = 1.5564 (slight rounding error)

X minus 1 plus 2 plus log x equals 3. find x?

Original Statement:x - 1 + 2 + log(x) = 3Simplify:x + 1 + log(x) = 3Subtract 1:x + log(x) = 2Lambert W-Function:x = (W(100*ln(10))/(ln(10)) = 1.7555794993... (rounded up).This considered log(x) to be base 10 log (x).
