Start by multiplying both sides by 30.

That will get rid of all the fractions

Hi   

Everyone knows that women are better drivers!  

That is why the insurance often costs less for women.  :D

And Rosala, most of the good cooks that I know are male.  

LOL

But Alan, there are doubles in there :/

On the web2 calc ^ looks like $$x^y$$

How did you know that was the equation Chris :/

I guess it is just one of life's mysteries.  :)

Thanks Dragonlance,

The interpretation that Desmos has made there is really weird! 

It has interpreted the capital Y as a little x an the cpaital X as a little y.   How very strange!  

Hi MathsGod1

 Yes, that is all correct!    

Umm let me see

$$\\4^2=16\\
\sqrt{16}=4\qquad $That is certainly true$\\
$But a square root is really a power of 1/2 so$\\
\sqrt{16}=16^{1/2}=4\\\\$$

I just had a thought, it will help you with equations too.  I think inverse is the right word  

6+5-5=6                  plus 5 is the inverse of minus 5

$$3*6\div 6 = 3$$        divide by 6 is the inverse of multiply by 6

$$(\sqrt{7})^2=7$$             square is the inverse of square root

$$\sqrt{17^2}=17$$               square root is the inverse of square

$$\\\sqrt[5]{12} =12^{1/5}\;\;and\;\;\\\\
(12^{1/5})^5=12^{5/5}=12\qquad $The power of 5 is the inverse of the fifth root$$

$$log_{10}10^7=7$$                   the log is the inverse of base number.  Again not wording this properly.

Yes, that looks excellent MG,

I do want you to get used to checking your answers though.  It makes it easier for me to check as well!

For these number questions I want you always to run the question through the forum calc at the end so that we can both see that the answers are the same.   

New one:

$$1\frac{3}{4}\times 7 +8^2-6\div \frac{4}{10}$$

1\frac{3}{4}\times 7 +8^2-6\div \frac{4}{10}

I have not worked this one through so I have no idea how nicely it will turn out,it is probably horrible   

What is 8 divided by 16 MG
