Lnx=-3

scZoUnD [109]

Answer:

because It's rounded to the nearest hundred place

Step-by-step explanation:

Given equation:

$\ln(x ) = - 3$

recall that,

$\ln(a ) = b \iff {e}^{b} = a$

remember, In is natural logarithm which is actually nothing but common logarithm with the base euler's number (e) . anyway rewriting lnx=-3 yields:

$\ln( x ) = - 3\\ \iff {e}^{ - 3} = \frac{1}{ {e}^{3} }$

1/e³ is approximately 0.0497870684..... , rounding it to the nearest hundred place would be 0.05 which is the same answer as your textbook .
