1. Move the decimal:
* Start with 179.0 (adding a decimal doesn't change the value)
* Move the decimal point to the left until you have a number between 1 and 10. You'll move it two places to get 1.79.
2. Count the moves:
* You moved the decimal two places to the left.
3. Write the exponent:
* Since you moved the decimal to the left, the exponent will be positive.
* The exponent is the number of places you moved the decimal, so it's 2.
4. Combine it all:
* The scientific notation for 179 grams is 1.79 x 10² grams.
