can someone help me plz. this does not make ANY sense?

Question

the problem is 4/s + 10/s^2. I have ready my book, and anything else I can find on the internet. I just can't figure out how to solve it and its very frustrating. Plz help.

Answer 1

4/s + 10/(s^2)
First, multiply 4/s by s/s
You get:
(4s)/(s^2) + 10/(s^2)
Now that you have a common denominator, you can add.
(4s + 10)/(s^2)

That's your answer.

Answer 2

As you have listed an expression, and not an equation, I'll assume the objective is to simplify. To combine those terms, they must have a common denominator. The least common denominator or 1/s and 1/s^2 is 1/s^2. So, to get 1/s to be over the same denominator, multiply the first term by 1. 1? Yes 1. 1 in the form of s/s. : ) Then add numerators. Watch.

4/s * (s/s) + 10/s^2 = 4s/s^2 + 10/s^2
= (4s + 10)/s^2

Now, if you meant to solve for s, you need an equation. If that's the case, shoot me an email.

Answer 3

if you add them, you have to have a common multiple on the bottom, which in this case is s^2 because both pieces can go into that. to get from s to s^2, you have to multiply by s. so s times s equals s^2. what ever you do to the top, you do to the bottom so multiply s times 4 and you get 4s. so now it is 4s/s^2. you just bring down the other part since it already had the common multiple, so it is 4s/s^2 + 10/s^2. just add the tops and bring down the bottoms so now you have 14s/s^2. you can simplify the s's so that you have 14/s is your final answer!!!

Answer 4

You have left something out of your question. Is "4/s + 10/s^2" on one side of an equation that you're supposed to solve? If so, you need to show us what is on the other side of the equation. How exactly is the problem stated?

Answer 5

What are you trying to do? Solve for s? If you're trying to solve for s you're missing the = sign what does that equal?
4/s+10/s^2= something

You can solve for s then but without an equal sign it doesn'treally make sense.

Answer 6

= (x / r) + (y / r^2) the problem
= 1/r + 1/r^2 = (r+1)/r^2 the rule
= r*(s)/(r*r) + (1/1)*t/r^2 the reason (n/n) = (1/1)
=(s*r)/r^2 + t/r^2 multiplying for easy view

Answer 7

An equation has to have an equal sign somewhere... Btw, isn't this an electrical engineering question???

Answer 8

4/s +10/s^2=

4s/s^2 +10/s^2= (get common denominator)

(4s+10)/s^2= (add num. & keep den)

2(2s + 5)/s^2 (factor out 2)

leave answer this way or rewrite it as:

(2/s^2)(2s+5)

Answer 9

Misprint
There is no mention of what to do to this.
If it is an equation then where is RHS?
