From Log to Exponential Expression?

Question

Change each log expression to an equivalent expression involving an exponent.

(1) logSUB(pi) (x) = 1/2

(2) In x = 4

What does "In" stand for?

Answer 1

(1) √π = x

(2) e^4 = x

ln is like saying log sub e. You don't write log sub e, instead you write ln.

The n stands for natural. e is the natural number, so ln literally means logarithm with a natural base.

Answer 2

1. pi^(1/2)

2. e^4

ln is natural log base e

Answer 3

#1

pi^0.5 = x

#2
ln is basically logbase e (aka natural log)
So that becomes e^4=x
