The temperature of the sun is 27 million degrees Fahrenheit. Use scientific notation to express the temperature.
Ipatiy [6.2K]

Answer:

A

Step-by-step explanation:

We know million has 6 zeros.

So, 1 million would be written as:

1,000,000

Similarly, 27 million would be written as:

27,000,000

We know writing a number in scientific notation would make this a decimal in 1 decimal place, so we would select "2.7" as the base of the scientific number.

Now, how many places to the right do we need to go (in 2.7) to make it 27,000,000?

Counting, we see:  7 places

So, power of 10 would be "7", thus we can write:

2.7*10^7

Answer choice A is right
