Question

True or false and explain.

1. Lnsqrt(X+5) = 1/2 Ln X+5
2. Ln^2(X-4) = 2Ln(X-4)
3. e^-(Ln3 = -3
4.e^(Ln2)x = 2X

Answer 1

1. Lnsqrt(X+5) = 1/2 Ln X+5\[\ln \sqrt{x+5}=\ln(x+5)^{1/2}\]

Answer 2

\[=\frac{1}{2}\ln(x+5)\] True

Answer 3

2. Ln^2(X-4)?

Answer 4

2. I don't get question

Answer 5

\[\ln ^{2(x-4)}\]?

Answer 6

close! but the X-4 is not in the exponent. just bring it down.

Answer 7

\[Ln^2(X-4)\]
