Explain how to solve 4^x + 3 = 7 using the change of base formula log base b of y equals log y over log b. include the solution for x in your answer. round your answer to the nearest thousandth.

Explanation:

Subtract 3 from the given equation and you have ...

  4^x = 4

Taking logarithms to the base 4, you get ...

  x = log₄(4)

Using the change of base formula, this is ...

  x = log(4)/log(4) = 1

  x = 1.000

answer: the answer to your question is parallel

x=30
