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

You can put this solution on YOUR website! (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.
