Question

Which is the best estimate for StartFraction (8.9 times 10 Superscript 8 Baseline) Over (3.3 times 10 Superscript 4 Baseline) EndFraction written in scientific notation?
3 times 10 Superscript 2
6 times 10 Superscript 2
3 times 10 Superscript 4
6 times 10 Superscript 4

Answer 1

(8.9×10^8)/(3.3×10^4) = (8.9/3.3)×10^(8−4) ≈ 2.7×10^4, which rounds to 3×10^4.
