F(x) = (x + 9) / 3 and g(x) = 3x - 9

f((g)x) = (3x - 9 + 9) /3 = 3x /3 = x

g((f(x)) = 3 (x + 9)/3 - 9 = x + 9 - 9 = x

Use logarithmic properties and the fact that ln(2) ≈ 0.69 and ln(3) ≈ 1.10 to approximate the value of each of the following log

bija089 [108]

Answer:

ln6 = 1.79

Step-by-step explanation:

The logarithm here has base e so it is a natural logarithm.

$log_ex=lnx$

$lnx=y\\\Rightarrow e^y=x$

According to the product rule of logarithms

$ln(a\times b)=ln(a)+ln(b)$

$6=3\times 2$

$ln6=ln(3\times 2)\\\Rightarrow ln6=ln3+ln2\\\Rightarrow ln6=1.10+0.69\\\Rightarrow ln6=1.79$

∴ ln6 = 1.79
