48 cubed = 48*48*48

Find factors of 48:
12 and 4
12*4=48

Neither of those numbers are prime factors so we have to break both of then down further.

Find prime factors of 4:
2*2=4

Find factors and prime factors of 12:
12= 4*3
3 is a prime factors but 4 is not. Break down 4 again and get 2*2*3=12

So put that all together and get the prime factors of 48, they are:
2*2*2*2*3

The prime factor of 48 cubed is the same thing as the prime factor of 48 three times

The prime factors are:
2*2*2*2*2*2*2*2*2*2*2*2*3*3*3
(12 2's and 3 3's)

Starting with:

\frac{2p}{p+1} +  \frac{3}{p-1} =  \frac{15-p}{p^{2}-1}

First, the difference of 2 squares shows that p^{2} - 1 = (p+1)(p-1)

Sub that in and multiply both sides by (p-1)(p+1):

\frac{2p(p+1)(p-1)}{p+1} +  \frac{3(p-1)(p+1)}{p-1} =   \frac{(15-p)(p-1)(p+1)}{(p-1)(p+1)}

This easily simplifies to 2p(p-1) + 3(p+1) = 15 - p

See if you can continue from here. If not, leave a comment and I or someone else can show you the rest.

Describe the pattern 0.13, 0.65, 3.25, 16.25
Oksi-84 [34.3K]

Let n be the current term and n+1 be the next term

Then the pattern is: n+1 = n * 5

Step-by-step explanation:

Given series is:

0.13, 0.65, 3.25, 16.25

We can find the ratio between consecutive numbers to find the pattern

So,

Ratio = \frac{0.65}{0.13}\\=5

We can see that multiplying the previous term with 5 gives us the next term

0.13 * 5 = 0.65

0.65 * 5 = 3.25

3.25 * 5 = 16.25

Let n be the current term and n+1 be the next term

Then the pattern is: n+1 = n * 5
