:-
x = ln 1•53
x = 0•425
eˣ = 1.53
ln(eˣ) = ln(1.53)
x ln(e) = ln(1.53)
x = ln(1.53)
x = 0.425 (to 3 sig. fig.)
natural log (ln) is the log of base "e", since so if you get the natural log of both sides, this cancels out the "e" on the left side which leaves you with just "x":
Now using a calculator we get:
0.425 (rounded to 3SF)
4.61817682
rounding:
4.61
I simply used the built-in calculator
No thanks. Logarithms are easy to solve.
