What is 400,000 in scientific notation? O A) 40 x 104
OB) 400 x 103
OC) 4 x 106
OD) 4 x 105

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.
