Question

Solve log2x = log53 + 1 by graphing. Round to the nearest tenth.

Answer 1

Answer: 3.2

Step-by-step explanation:

Answer 2

Answer:

3.2

Step-by-step explanation:

This is the correct answer on ed-genuity.

To find the answer, first change both sides of the equation into change of base formula. You'll end up with:

$y_{1} : \frac{logx}{log2} \\y_{2} : \frac{log3}{log5} + 1$

When you plug these into a graphing calculator, like the one rd-genuity gives you, you'll get 3.2 as the x-value of where the two lines intersect (rounded to the nearest tenth).

Hope this helps! :)
