What is 2140000000 in scientific notation?

Answer 1

To write a number in scientific notation, we first need to multiply the number by a power of 10 to get a result that has units as the biggest value digit. In this case, we need to multiply by 0.000000001 to get 2.41

We multiplied by 0.000000001 and that is the negative 9th power of 10, or 10-9, so we need to add this to 2.41 as a multiplication.

Thus 2140000000 in scientific notation is 2.41x10-9
