# How do you express 2650000 in scientific notation?

The decimal point is (invisibly) to the right of the final $0$. Leapfrog it from there left, counting the jumps, until it is to the right of the leftmost number ($2$). There are $6$ jumps, so we write: $2.65 \times {10}^{6}$ (no need to include the trailing zeroes).
