\(\frac{5409}{4} = 1352 \frac{1}{4}\) or 1352.25

I hope this helps :)

First, break up the number into it's prime factors and put everything under the radical.

\(\sqrt{48} = \sqrt{2*2*2*2*3}\)

Then find the pairs, pull them out of the radical, and multiply the radical by that number.

We have 2 pairs of "2s" in the prime factorization of 48, so after removing them, we get

\(2*2\sqrt{3}\) which simplifies to \(4\sqrt{3}\)

Or you can try and factor the original number into perfect squares, for example

\(\sqrt{48} = \sqrt{4*4*3}\) and since √4 is equal to 2, you can remove the √4s inside the radical and replace them with "2s" outside the radical. Both ways will ive you the same answer.

If this was not clear, (I understand if it isn't) speak up so somebody can clarify.

I hope you find this helpful! :)

\(\frac{3}{29} \) * 100% = 10.345%

81.9 * \({10}^{-3}\)is not proper scientific notation.

The first number must be equal to or greater than 1, but less than 10.

What you're talking about is supposed to be \(8.19 * {10}^{-2}\) in proper scientific notation.

If you want an answer, we need more details.

1.83 tons is a lot heavier than 2.0 Kilograms, but 1.83 ounces is considerably less than 2.0 pounds.

Give us units to match the numbers! If it's the same unit, common sense ought to tell you that 1.83 < 2.0.

I'm not sure why there's a " - " sign stuck in between " 2+-1.25 "

but other than that, you are absolutely correct!

2 - (-1.25) = 2 + 1.25 = 3.25

= 2/7

 1 3/7 = 10/7

10/7* 1/5 = 10/35

10/35 = 2/7

Hope this helps.

= 13

1.75(-4) + 20

-7 +20

13

! In math means factorial.

When talking about integers, it means multiply all the positive integers that appear before it.

For example: 2! = 2*1

3! = 3*2*1 = 6

4! = 4*3*2*1 = 24

5! = 5*4*3*2*1 = 120

and so on.

It's used in combinatorics and probablility. It's also a way to tell how amny possible ways there are to arrange n number of objects.

I hope this helps!

You're very welcome! We're glad to be a help and we try our best! =)
