A spacecraft is orbiting Mars. At the farthest point in its orbit, it is 76,994 kilometers from Mars. Which of the following numbers is 76,994 written in scientific notation?
Answer choices:
A)7.6994 x 10 to the 4th power
B)7.6994 x 10 to the 5th power
C)7.6994 x 10 to the 6th power
D)7.6994 x 10 to the 3rd power
(Not sure why Brainly doesn't allow exponents)

Answer 1

So scientific notation is
(number>1 and <10) times 10^xpower

so count how many decimal places the decimal needs to move to make 76994 >1 and <10
it needs to move 4 places so
7.6994 times 10^4
the answer is A
