I also need help with this one:

Add. Express answer in simplest form.

((8)/(s))+ ((8)/(s^2))

(8s + 8)/s^2 = 8(s+1)/s^2
That isn't much simpler than the original form, but sometimes they want single denominators.

wouldn't it be :

(8s+8)/s^2

To add the fractions ((8)/(s)) and ((8)/(s^2)), you need to find a common denominator and then combine the numerators.

Let's start by finding the least common denominator (LCD) of the two fractions. The LCD is the least common multiple (LCM) of the denominators, which in this case is s^2.

To convert the first fraction ((8)/(s)) to have a denominator of s^2, you need to multiply both the numerator and denominator by (s), which gives you ((8s)/(s*s)) or (8s/s^2).

The second fraction ((8)/(s^2)) already has the desired denominator, so there's no need to change it.

Now, you can add the fractions since they have the same denominator:

(8s + 8)/s^2

The numerator can be simplified further by factoring out a common factor of 8:

8(s + 1)/s^2

So, the sum of the fractions ((8)/(s)) and ((8)/(s^2)) can be expressed in simplest form as (8(s + 1))/s^2.
