What is 3,463,000,000 in scientific notation?

In scientific notation, you want to express your number as a sign and number between 0 and 10 times an exponent of 10.
So 3,463,000,000 becomes 3.463 x 10^9.

The 10^9 is the number of positions the decimal point shifts to the left. We're multiplying by 1,000,000,000.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
