Thank you. My teacher only taught sig figs with a video, and it didn't cover scentific notation.

How many Sig Figs are in \( 3.4\times {10}^{4}\)

Significant firgues with scientific notation is very easy. There are 2 digits in 3.4 so there are 2 significant figures.

Only the significant part should be written in sci fi although if there is more to the question (like you have worked out the number yourself) you may need to be careful.

3.40000 * 10^4 has 6 significant figures
