Math problem

Answer 3

@ankolix Please don't just give out answers. It doesn't help the asker in solving future questions like this.

Answer 4

A more in-depth solution:

log 8x^3 = 4
Since 8 = 2^3 (if you don't already know this, memorize it!),
log (2x) ^3 = 4
3 log(2x) = 4
log(2x) = 4.

You should be able to solve this from here.

Answer 5

x=5000 right?

Answer 6

@tyteen4a03

Answer 7

Wolfram|Alpha gave me something else.

Answer 8

Answer 9

Hint: it is not a whole number.

(Oh, and in case you were wondering, my last step is wrong. It should be log(2x) = 4/3. Sorry!)

Answer 10
