Question

11. In scientific notation, (6.2 x 104) x (3.3 x 102 ) equals ____________________.

Answer 1

6.2*3.3=20.46
Since it is multiplication with scientific notation, you are adding the exponents, so it would be 4+2, being 6.
20.46*10^6. However, scientific notation says that the first number cannot be larger than 9.9, so, you must move a decimal. 2.046*10^7

Answer 2

Thanks!
