Multiply 3.4 x 10^6 and 2.1 x 10^9

Answer 1

To multiply numbers in scientific notation, you multiply the coefficients and add the exponents.

First, multiply the coefficients:
3.4 x 2.1 = 7.14

Next, add the exponents:
10^6 x 10^9 = 10^(6+9) = 10^15

Putting it all together, the product of 3.4 x 10^6 and 2.1 x 10^9 is:
7.14 x 10^15
