Question

What is the solution of the equation 2X = 7? Round your answer to the nearest ten-thousand.

Answer 1

x =2.8074

Explanation:

2^x = 7

Take the log of each side

log (2^x) = log (7)

We know log a^b = b log a

x log 2 = log 7

x = log (7) / log 2

x =2.80735

To the nearest tenth thousandth

x =2.8074
