What's is (7x10^5) x (3x10^2)

Mathematics
1 answer:
denpristay [2]2 years ago
8 0

Answer:

If you expand that, it comes out to 200000000, or in scientific notation, 2.0 × 10⁸.

Step-by-step explanation:

Starting with:

(7 × 10⁵) × (3 × 10²)

Since everything is multiplied, we can drop the brackets:

= 7 × 10⁵ × 3 × 10²

Now we can multiply seven by three, and both powers of ten:

= 20 × 10⁷

We can expand this now as

200000000

or in proper scientific notation:

2.0 × 10⁸

How do u round 33 and 89 to estimate their sum
Zolol [24]
33 would round down. (30)

This is because the second 3 is smaller than 5 and when your rounding, if number your rounding is smaller then 5 you will round down

89 would round up. (90)

This is because the 9 is larger than 5 which means you would round up.

Solve the M <br> -5 m = -35
dedylja [7]

Answer: <em>m = 7</em>

Step-by-step explanation: In this equation, since a -5 is being multiplied by <em>m</em>, in order to get <em>m</em> by itself, we must divide both sides of the equation by -5.

On the left side, our -5's cancel out and we are left with <em>m</em>. On the right side, -35 ÷ -5 gives us 7. So m = 7.

To check our answer, we plug 7 back in for <em>m</em> in the original equation and we get -5 (7) = -35 which is a true statement so we know our answer is correct.

Don't just do this problem in your head. It's extremely important to develop the habit of putting all your steps down on paper or digitally. It will really pay off for you down the line.
