A seed weighs 0.00002421 ounces. What is this value in correct scientific notation? A) 2421 x 108
B) 2.421 x 105
2.421 x 10-5
D 2421 x 10
-8

d/

Step-by-step explanation:

C) 2.421 x 10^-5

Step-by-step explanation:

A negative exponent on a power of ten will make the decimal point go back that amount of times to the left, making it a lesser number. A positive exponent will cause it to move to the right, making the number greater. We aren’t going to need to make any of the numbers being multiplied greater, so we can eliminate the first two. Then we need to solve the others. We can do this by moving the decimal the amount of times that we see the exponent equals. Since C is -5, we move it to the left 5 times, and get the weight of the seed; 0.0002421.
