How do you change 154155500 into a scientific notation?

Answer 1

In this case, one is still following the same rules that apply for scientific notation which are:

*If there is no decimal, it is understood to be at the end of the number.

*The goal is to reach a nonzero numbers; in large numbers such as this, it is the first number in the set and in numbers that begin with a decimal, it is the first nonzero number shown.

-Count the number of spaces or jumps needed to get from the end of the number to the nonzero number, remembering to include all numbers before it.

-The number being multiplied by the base ten has to be 1-9

- The exponent of the base 10 depicts the number of jumps; positive exponents depict going from a larger to smaller number such as in this case and nenegative exponents depict a transition from a smaller to larger number.

Since this number includes multiple nonzero numbers, the goal is to include all but the zeroes in order to keep the number the same. Counting the numbers from the understood decimal at the end to the space after the first number counts 8 making the exponent 8, and since one is going from large to small, the exponent is positive:

1.541555 x 10^8
