Question 207174: could someone please help me solve these problems so i can help my daughter understandit better.Thanks for your time.

1. m^3 x n^3 (x is times symbol)
2. 2(square root symbol) + 3(square root symbol) x
3.x^2-x^3
4.(x+y)^5
---------
(x+y)^4

thanks for the help and if you can please write out the problem so that the next time i"ll know how to write it so it's easily understood.hagd Sarah

(1),,, m^3 * n^3= (mn)^3
.
m^3 =m*m*m,,,,,,n^3=n*n*n,,,,,
.
m^3*n^3 = m*n*m*n*m*n = (mn)^3
.
.
(2),,,2*sqrt(x)+3*sqrt(x) =5*sqrt(x)
.
.
(3),,,x^2-x^3,,,that's as simple as it can be
.
(4),,,,(x+y)^5 / (x+y)^4 = (x+y)^{5-4} = (x+y)^1= x+y
.
ex,, x^5 / x^4 =(x*x*x*x*x)/(x*x*x*x*)= x
.
that is, to divide like terms with exponents, subtract exponents.
.
.
.
Likewise, to multiple like terms with exponents, add exponents.

1. m^3 x n^3 (x is times symbol)
-----

example:

-----
2. 2(square root symbol) + 3(square root symbol) x
-----
i think what you are saying here is
if so, this would be equal to which would be equal to
example:
= = =
= = =
-----
3. x^2-x^3
-----
=
example:
= = =

-----
4.(x+y)^5
---------
(x+y)^4
-----
i believe this is which is equal to which is equal to which is equal to
example:
= = =
= = =
