### Use the associative law of multiplication to write an equivalent expression. 5[x(2 + y)]

5[x(2 + y)] = (5x)(2 + y) Note that we are to use associativity of multiplication and nothing else. Thus, do not distribute 5x into (2 + y).

### Prove the third law of exponents

The meaning of x^(m/n) I guess is the third law. x^(1/n) means the n-th root of x. If y=x^(1/n) then y^n=x. So y is the n-th root of x. This is the same as x^(1/n*n)=x^1=x. y^m=(x^(1/n))^m=x^(1/n*m)=x^(m/n). This is the same as (the n-th root of x) raised to the power m; or it is the n-th r
