Question 251206: Please help I am really confused and could use a step by step break down.
Solve. Where appropriate, include approximations to the nearest thousandth. If no solution exists, state this.
ln (2x + 3) = 2

Solve. Where appropriate, include approximations to the nearest thousandth. If no solution exists, state this.
log2√x^2-4 = 1

Solve. Where appropriate, include approximations to the nearest thousandth. If no solution exists, state this.
ln (2x + 3) = 2
Find antilog () of both sides
2x + 3 = 7.389
2x = 7.389 - 3
2x = 4.389
x =
x = 2.195

Check this: enter into your calc: ln(2(2.195)+3) ans 2.000 confirms our solution

Assume you mean this is a base 2 log
Write the exponent equiv of logs

Which is:
2 =
square both sides
4 = x^2 - 4
8 = x^2
x =
x =
or
x = 2.828
