If you have questions on this or any other math problem feel free
to let me know how to contact you.......Read Below.......
I tutor free online since moving to France from Florida in June 2011.
Hope this is most helpful and you will continue to allow me to tutor you.
If you dont fully understand or have a question PLEASE let me know
how to contact you so you can then contact me directly with any math questions.
If you need me for future tutoring I am not allowed to give out my
info but what you tell me on ***how to contact you*** is up to you
Been a pleasure to serve you Please call again

A PRESENT FOR YOU
Ask someone to write a number, say a five-digit number.
(Can be a 2-digit.....3-digit.....4-digit....ect..…
Suppose the number written is
57836
Now, without showing the asker, you write a number on
a sheet of paper and keep it folded. You have to write the
number by subtracting 2 from the above number and
adding 2 in front which will be....
257834
Next, ask the person to write another five-digit number
below his original number. Suppose he writes 37589.
So you now have...
57836
37589
Now you write a five-digit number below it in such a
way that each digit is 9 minus digit above. You now have...
57836
37589
62410
Ask the person to add one more 5-digit number. If he
adds 54732, you add below it 45267. Note that you decided
the number by subtracting each of his digit from 9.
Thus, you now have.....
57836
37589
62410
54732
45267
Next, ask him to add all the number and he gets 257834
Show him the number which you had written as an answer
to this addition earlier in the folded paper and surprise him.
b) 18 x^9 y^8

a) 3y^4.....Divide coefficients and subtract exponents when you divide,
b) 18x^9y^8...Multiply coefficients and add exponents when you multiply,
Simple, right?

a) 21y^13/7y^9
= (21/7) * (y^13 / y^9)
= 3 * y^(13-9)
= 3y^4
b) (3x^5)(x^2y^4)(6x^2y^4)
= (3*6) * (x^5 * x^2 * x^2) * (y^4 * y^4)
= 18 * x^(5+2+2) * y^(4+4)
= 18x^9y^8
= (21/7) * (y^13 / y^9)
= 3 * y^(13-9)
= 3y^4
b) (3x^5)(x^2y^4)(6x^2y^4)
= (3*6) * (x^5 * x^2 * x^2) * (y^4 * y^4)
= 18 * x^(5+2+2) * y^(4+4)
= 18x^9y^8

a) basic reduction. 7 goes into 21 three times. top would be 3y^13/y^9. because there are 4 more "y" on top you subtract them and 13-9=4 so answer is 3y^4
b) multiply it out
18x^9y^8
b) multiply it out
18x^9y^8
