    okay and for the second one would it just be 1^-1?

    no look again 1 is not x hint x^0 = 1

    so it would be 0^-1 right? or just x^-1?

    \[1.) x ^{3/4}\] \[2.) \frac{ 1 }{ x ^{-1} } = x ^{-1(-1)}= x ^{1}= x\] \[3.) x ^{5/10}* x ^{4} * x ^{3} = x ^{1/2}*x ^{4}*x ^{3} = x ^{(1/2)+(4)+(3)} = x ^{15/2}\] \[4.) x ^{1/3} * x ^{1/3} * x ^{1/3} = x ^{(1/3)+(1/3)+(1/3)}= x ^{3/3}= x ^{1}=x\]

    is that how to simplify all of them? now how do I compare to see which ones are equal?

    so, 2 and 4 would be equivalent right?
