Question

Solve 4 ln x=2ln25
A) x=5
B) x=25
C) x=625

Answer 1

the answer is A x=5

Explanation:

the answer to the second part is B x=6

Answer 2

A) x=5

Explanation:

4 ln x=2ln25

Replace 25 with 5^2

4 ln x=2ln (5^2)

We know that ln a^b = b ln a

4 ln x =2 2ln 5

4 ln x = 4 ln 5

Divide by 4

4/4 ln x = 4/4 ln 5

ln x = ln 5

x = 5
