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

90,000

Step-by-step explanation: First let's figure out .

We know that 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 × written in standard notation is 90,000

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
