A dinosaur fossil is 93,550,000 years old. How can you express this age in scientific notation
garik1379 [7]

1. 9.355 × 10^{7} can be used to express the age of the dinosaur fossil.

Step-by-step explanation:

Step 1; To determine which value is the closest to 93,550,000 we must calculate how much the 4 options equal. If there are decimals in the number, they are moved from the decimal part of the number to the integer part with every power of 10 i.e. 2.4 × 10 = 24, 2.44 × 10² = 244.

Step 2; Now we determine how much the 4 options equal.

1. 9.355 × 10^{7} = 93,550,000.

2. 9 × 10^{7} = 90,000,000.

3. 9.36 × 10^{7} = 93,600,000.

4. 9.3 × 10^{7} = 93,000,000.

Out of the four options, option 1 equals the value of 93,550,000. So option 1 can be used to express the age with the highest precision.
