Final answer:
To multiply numbers in scientific notation and convert the result to standard form with 3 significant figures.
Step-by-step explanation:
To multiply two numbers in scientific notation, multiply the coefficients and add the exponents, while taking care to apply the rules of significant figures. First, multiply the coefficients: 3.56 x 5.87 = 20.9252. Next, add the exponents: -5 + 12 = 7. The result is 20.9252 x 10^7. Finally, convert the result to standard form with 3 significant figures: 2.09 x 10^8.
