\(0.29\cdot(1.046)^{t} = 0.60\) Solve for 't'. You will need logarithms.

Introduce the logarithm \(\log\left(0.29\cdot(1.046)^{t}\right) = \log(0.60)\) Now what?

"I think the answer is..." is not ever an acceptable response. In mathematics, you must prove it. Use the logarithm rules. There is a reason why we did that massive problem, before. \(\log(0.29) + t\cdot\log(1.046) = \log(0.60)\) You need to see where ALL of this came from.

Solve for 't'. You must be able to do this. This is why we invented notation. It will help you. Use the notation, and proper operations on that notation, to solve for 't'. Let's see what you get.
