Mary is solving the equation 2^n – 3 = 83. Her first three steps are shown:

Step 1: 2n – 3 = 83
Step 2: 2n = 86
Step 3: ln 2n = ln 86

Which shows Step 4?

ln 2 = n ln 86

n + ln 2 = ln 86

n ln 2 = ln 86

n = ln 86 – ln 2

$$\huge\rm 2^{n}-3=86$$ is this ur question ?
n is exponent right ?

nnesha · Answer

power rule $$\large\rm log_b x^y = y \log_b x$$

anonymous · Answer

yes thank you

nnesha · Answer

$$\huge\rm ln 2^n =\ln 86$$
next u should apply the power rule
