Question

Write 124 in scientific notation.

Answer 1

1.24 ×10²

Explanation:

Always keep one digit number (from 1 - 9) behind the decimal.

And add "×10" with the power of how many decimals it took to go from right to left.

124.

12.4 (one)

1.24 (two)

So the power is ².

1.24 ×10²

Answer 2

Explanation:

Write 124 in scientific notation.

Then, in scientific notation, 124 is written as 1.24 × 102. Actually, converting between "regular" notation and scientific notation is even simpler than I just showed, because all you really need to do is count decimal places.
