Answer 6

hehe

Answer 7

II, III, I, IV, V

Answer 8

this is an example by the way

Answer 9

i already know the answer to it

Answer 10

i just dont understand how people got it

Answer 11

did you get the picture

Answer 12

A picture of an algebra problem or of a geometry problem?

Answer 13

geometry, the link sends you to the triangle

Answer 14

this is algebra

Answer 15

If one dimension is 3 and the other is sqrt(3), the area is 3sqrt(3). Because sqrt(3) is irrational, the area 3sqrt(3) is also irrational.

3*4 would be rational.
3*2.5 would be rational.
But 3sqrt(3) is irrational.

Answer 16

To answer this short set of questions properly, you need to know the precise definition of "rational." What is that def'n?

Answer 17

def of what ?

Answer 18

definition of the word "rational."

Answer 19

"A rational fraction is one in which ... what?"

Answer 20

for example 1/2 is rational it = 0.5

Answer 21

1/2 is rational, but not because it equals 0.5.

1/2 is rational because it's the ratio of two integers. 1 is an integer and 2 is also.

Answer 22

okay

Answer 23

Look up "rational number" on the Internet for more examples.

Answer 25

sqrt(3) cannot be written as the ratio of two integers. That's why it's not rational. We say it's "irrational."

Answer 26

Regarding \[8^{\frac{ 1 }{ 3 }}\]

Answer 27

You could re-write that in "radical form," which would be \[\sqrt[3]{8}\]

Answer 28

Notice that this is a radical, and the "index of the root" is 3.

That's why 8^(1/3) is called the "cube root of 8."

Answer 29

okay well i get all that but did i show enough work?

Answer 30

@mathmale

Answer 31

It's not a matter of "showing enough work." The "work" has to be correct. I would not say that the explanation I gave you is the only possible one. However, I reviewed a concept that you need to know: that exponential functions can be expressed as radicals and radical functions can be expressed as exponential functions.

Answer 32

We are expected to explain why\[8^{\frac{ 1 }{ 3 }}\]

Answer 33

yes i know, to me i think i explained it pretty well, what do you think

Answer 34

is called the "cube root of 8." As before, I made use of the equality\[8^{\frac{ a }{ b }}=\sqrt[b]{8^a}\]

Answer 35

That is what you have to show. It's a test of your understanding of this concept.

Answer 36

Excuse me, y ou got Part A done just fine.
What do you need to discuss or learn right now?

Answer 37

geometry @mathmale i will make new post

Answer 38

In the first and only geometry problem you've shared with me, your job was to arrange the 5 steps in the proof in correct order. I overlooked that at first.
