T=0.4254

Explanation:

As 2=5.1^T

T=log_5.1 2

= log2/log5.1

= 0.3010/0.7076

= 0.4254

T = (log(2)) / (log(5.1))

Explanation:

We have: 2 = (5.1)^(T)

Let's apply logarithms to both sides of the equation:

=> log(2) = log(5.1^(T))

Using the laws of logarithms:

=> T log(5.1) = log(2)

We can finally solve for T by dividing both sides by log(5.1):

=> T = (log(2)) / (log(5.1))
