x = 1 over 3
x = 1
x = 7 over 3
x = 4

Best ResponseYou've already chosen the best response.0Is this correct? \[\Large \log (2x3^{125}) = 3\]

Best ResponseYou've already chosen the best response.0@telltoamit Only @gioanny39x can say that for sure. Gio, you need to confirm if I have the equation correct or not. Also, your formula is wrong. \[\Large log_B(X) = Y\] is the same as \[\Large X = B^{Y}\] Example: \[\Large log_10(1000) = 3\] B = 10 X = 1000 Y = 3 Using the 2nd form of the equation: \[\Large X = B^{Y}\] \[\Large 1000 = 10^{3}\]

Best ResponseYou've already chosen the best response.0Ok, so: B = 2D3 (easier to use D to not confuse with X) X = 125 Y = 3 \[\Large X = B^{Y}\] \[\Large 125 = (2D3)^{3}\] Solve for D. Hint: 125 is the cube of a single digit number.

Best ResponseYou've already chosen the best response.0You're creating too much work for yourself. What is the cube root of 5? Hint: \[\Large X^{3} = (15Y+5)^{3}\] \[\Large X = (15Y+5)\] If you have two items that when cubed equal each other, the items equal each other.
