Question

Write the number in standard notation. 9 × 10 to the power of 4

Answer 1

Answer:

90000

Step-by-step explanation:

9 x 10 (to the power of 4)

move the zeros to the right side four time, because the power of 4 is positive.

Answer 2

Answer: 90,000

Step-by-step explanation: First let's figure out $10^{4}$.

We know that $10^{4}$ means 10 · 10 · 10 · 10.

So let's start with the decimal 1.0.

The exponent of 4 tells us to move the

decimal point 4 places to the right.

Now, we fill in the missing positions with zeroes.

When we do this, we get 10,000.

So now we simply have 9 · 10,000 which is 90,000.

If you would like you could also just do 10 · 10 · 10 · 10 and multiply these numbers to get 10,000. If would recommend using the method I used because it's easier and doesn't require much work.

So 9 × $10^{4}$ written in standard notation is 90,000
