Q. At 2.4×1082.4 \times 10^8 years old, the Nyasasaurus parringtoni may be the oldest known dinosaur that lived on Earth. How many millions of years old is it?\newline\newline____ million years old\newline
  1. Convert to Millions: Convert the scientific notation to millions by moving the decimal point 66 places to the left, because 11 million is 10610^6.\newlineCalculation: 2.4×108/106=2.4×108−6=2.4×1022.4 \times 10^8 / 10^6 = 2.4 \times 10^{8-6} = 2.4 \times 10^2.
  2. Calculate Simplification: Now simplify the expression 2.4×1022.4 \times 10^2.\newlineCalculation: 2.4×100=2402.4 \times 100 = 240.
