[39 points] if what is

Given

x^5*k=a .................(1)

x^2*k=b .................(2)

We need to find x^3.

Solution:

On inspection, we note that (1)/(2) gives x^3 on the left hand side, but the division is valid on conditions that x ≠ 0 and k ≠ 0.

So we conclude:

(1) / (2)

=>

=>

on condition that and

Remark.

The easiest way to do this is simply to leave the givens alone and divide. Parts of it will cancel out. You can't always do this, but this question is an example of leaving things be.

Step One

Divide the two expressions

Now you use the index laws to get what you need. Forget the ks on the left for a second and just work with the xs.

The law of indices says that it you want to bring the power of the same base to the numerator, you write the base in the numerator, and subtract the power that was in the denominator from the power in the numerator. x^(5 - 2) in this case.

Step Two

Next deal with the ks.

The same law applies for the ks. You subtract the power shown in the numerator from the power of the k in the denominator, in this case 1/k^(2 - 1)

Step Three

The last step is to multiply both sides by k

Giving as your final answer

answer: idk

step-by-step explanation:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
