Best ResponseYou've already chosen the best response.1Well Lets try to isolate x So first we subtract 50.001 from both sides logx=53.001

Best ResponseYou've already chosen the best response.0i typed it wrong, its base x+5 to the 0.0013

Best ResponseYou've already chosen the best response.1Then we know that \( e^{ \log{x}} =x\) So \( e^{ \log{x}}=e^{53.001}\)

Best ResponseYou've already chosen the best response.0@shannondidier What should we use as the base of the unspecified "log?" Some people interpret this as log base 10, others interpret it as the natural log (base e)

Best ResponseYou've already chosen the best response.1Seems like the base is x+5 not 10

Best ResponseYou've already chosen the best response.2so it is asking us to find a value \(x\) such that \[(x+5)^{3} = 0.001\]

Best ResponseYou've already chosen the best response.2Here's a hint: \[x^{n} = \frac{1}{x^n}\] and \[0.001 = \frac{1}{1000}\]

Best ResponseYou've already chosen the best response.0yeah i understand that. so whats the final answer?

Best ResponseYou've already chosen the best response.2okay, look at your answer choices. do any of them + 5 = a number that when raised to the 3 power = 0.001, or when raised to the 3 power = 1000?

Best ResponseYou've already chosen the best response.2maybe work backwards — what number cubed gives you 1000?

Best ResponseYou've already chosen the best response.0x = 5 x = 7 x = 13 x = 15 would it be x=5

Best ResponseYou've already chosen the best response.2it would! \[(5+5)^{3} = 10^{3} = \frac{1}{10^3} = \frac{1}{1000} = 0.001\]
