Question

Which number is not in scientific notation?

1.1 ⋅ 10213
7.8 ⋅ 108
3.02 ⋅ 10−10
35 ⋅ 104

Answer 1

thoughts?

recall that scientific notation takes the form

A * 10^(B)

where A is a number at least 1, but less than 10 (so 1 up to 9.9999 etc.)
and B is a positive or negative integer exponent

using this logic, which answer choice *doesn't* fit the definition of scientific notation?
