log4(x) +16 +log4(x) +4=3

2log4(x)=-17

log4(x)=-17/2

x=4^(-17/2)

=========================

Since the parentheses have been lost from the question,

it could easily be interpreted this way instead, (as well as

a few others):

x log(4x) + 16 + log(4x) + 4 = 3

(x + 1) log(4x) = -17

4x = 10-17/(x+1)

4x = the (x+1)th root of 10-17

Come on back and solve that one for us.

Same as log(5x2) = log(10).

2 log(x) + 3 log(x) = 105 log(x) = 10log(x) = 10/5 = 210log(x) = (10)2x = 100

x = 3*log8 = log(83) = log(512) = 2.7093 (approx)

You calculate a log, you do not solve a log!

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.

The explanation and answer to the following math equation to find x -0.3 plus 5-5 log (d) equals a plus 5-5 log 4 (d) is -5 log(d)+x+4.7 = a-5 log(4 d)+5. The solution is x = a-6.63147.
