Question

Solve. 64 = 16

Answer 1

How do I work this out?

Answer 2

No unknown(s), How can we solve?

Answer 3

it's an Exponential Equations. These are my options:
x = -2
x = -1
x = -(1/4)
x = -(1/3)

Answer 4

And where is the unknown?

Answer 5

\[64^x =16\] or \[64 = 16^x\]?

Answer 6

There's the problem! The instructor didn't add in any subscripts or unknowns!

Answer 7

Alright, tell him/her that there are some problems with the question.
Let's try to solve both and see which gives you the answer from the options
For the first one,
\[64^x =16\]\[(2^6)^x =2^4\]\[2^{6x} =2^4\]\[6x=4\]\[x=\frac{2}{3}\]
For the second one,
\[64 =16^x\]\[(2^6) =2^{4x}\]\[6 =4x\]\[x=\frac{3}{2}\]
So, neither of the equation is the one your instructor wants to set :|
Sorry...

Answer 8

It's alright. Thank you for trying it out anyways
