5x4 = 20

20-10 = 10

10+90 = 100

$${\frac{{\mathtt{3}}}{{\mathtt{4}}}}{\mathtt{\,\times\,}}\left({\frac{{\mathtt{10}}}{{\mathtt{3}}}}\right) = {\frac{{\mathtt{5}}}{{\mathtt{2}}}} = {\mathtt{2.5}}$$

If I understand your question correctly,

$${\frac{{\mathtt{2}}}{{\mathtt{0.03}}}} = {\frac{{\mathtt{200}}}{{\mathtt{3}}}} = {\mathtt{66.666\: \!666\: \!666\: \!666\: \!666\: \!7}}$$

Gotta be a huge bug LOL because it doesn't want to accept any answers 

I don't know what to tell you.....maybe there's a "bug" in the system......LOL!!!

Thanks CPhill, I tried that too and it doesn't work. I think I give up LOL

We need the slope and a point to write an equation.....the slope is

[5-3] / [2 - 1]  = 2/1 = 2

And using the point-slope form, we have

y = 2(x - 1)  + 3 

y = 2x - 2 + 3

y = 2x + 1

Note that we can check this with the other point

y = 2(2) + 1  = 5

So.....when x = 2, y = 5......as expected.......

.1929  = 19.29%

Mutiply both sides by the denominator on the left

l 5 + ^x√-177147 l = (2√5 - 4) (√5 + 2)

l 5 + ^x√-177147 l = 10 - 8

l 5 + ^x√-177147 l = 2   

This says that either

-(5 + ^x√-177147 )  = 2     or  (5 + ^x√-177147 )  = 2

Working with the first we have

- ^x√-177147  = 7

^x√-177147  = -7

-177177 = (-7)^x   .....and this has no real solutions

Working with the second, we have

 ^x√-177147 = -3

(-3)^x = -177147

Note that, we cannot take the log of both sides here because log(-3)^x would be undefined as well as log(-177147)

However.......if this has an integer solution, x must be an odd number....

So we can write

(-1)^x (3)^x  = -177147

And, if x is an odd integer, (-1)^x = -1.....so we have

(-1) * (3)^x  = -177147   divide both sides by -1

(3)^x  = 177147

Now...take the log of both sides....and using a log property, we have

x log3  = log 177147   divide both sides by log 3

x = log 177147 / log 3 =  11

Yes, it can only be divided evenly by 1 and itself.

first multiply both sides by the denominator on the right.

Then subtract 5 from both sides.

This should give you a radical to the x^th root of -177147 = -3

Then take the log of both sides. ..and multiply by -1.

log 177147=log 3^x

5.248=x log 3

x= 11

Is it possible to convert the 0.1929 ? 

That looks like a different question.

In your second case, it appears that you have been asked to convert to a percentage (to two decimal places).

I'm not sure why it says it's wrong. Something must be wrong with the Math website if it's not accepting my answer. I did another 0.8190 and my answer 81.90 was accepted. 

$${\frac{{\mathtt{1\,000\,000\,000}}}{{\mathtt{1\,466}}}} = {\mathtt{682\,128.240\: \!109\: \!140\: \!518\: \!417\: \!5}}$$

If you convert both numbers to decimals it makes it easier.

$$2\frac{1}{2}=2.5$$

$$\frac{2}{5}=0.4$$

2.5-0.4= 2.1 (The female fish is this much longer).

[2 + 1/2 ] - 2/5  =

5/2 - 2/5     =

25/10 - 4/10  =

21/10 inches =

2.1 inches longer

It's not wrong.....!!!!

.1929 to two decimal places  IS .19

We look to the digit past the first 9....since this is 2, we leave the 9 as it is......

why is it wrong?

$${\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{4\,000}}}}$$

To simplify $${\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{4\,000}}}}$$ in exact form:

1.  Break $${\mathtt{4\,000}}$$ into its simpliest multiples: $${\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{5}}}}$$

2.  How many of the same number under the radical do you have?:  Five $${\mathtt{2}}$$'s, Three $${\mathtt{5}}$$'s

3.  Wherever you see three of the same number pull those two numbers out:  $${\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{2}}}}$$

4.  Multiply the remaining numbers under the radical and numbers ouside the radicall: $${\mathtt{10}}{\mathtt{\,\times\,}}{\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{4}}}}$$

$${\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{4\,000}}}}$$ simplified in exact form is $${\mathtt{10}}{\mathtt{\,\times\,}}{\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{4}}}}$$

In its approximate form: $${\sqrt[{{\mathtt{{\mathtt{3}}}}}]{{\mathtt{4\,000}}}} = {\mathtt{15.874\: \!010\: \!519\: \!681\: \!994\: \!7}}$$...

¹¹√[-177147 ] = -3   .... so we have

 l 5 - 3 l / [2 + √5 ] =

2 / [2 + √5 ]      rationalizing the denominator, we have

2 [2 - √5 ] / [ - 1 ] = 

2√5 - 4   =

 about . 472

I get 0.47.

I don't know if I could have determined the 11th root without a calculator.
