    all of the numerator is to the third power

    \[(t-7)^{3/2} \over (t-7)\]

    @purplec16 sqrt(t-7) is the simplified ans.

    wait...that cant be the answer cause its a limit and we dont want it to equal to 0

    limits are allowed to be zero

    step1: sqrt((t-7)^3)/t-7 step2: ((t-7)^(3/2))/t-7 step3: ((t-7)^(3/2))*((t-7)^-1) (because 1/a=a^-1) step4: (t-7)^((3/2)-1) (because (a^m)*(a^n)=a^(m+n)) step5: (t-7)^(1/2) step5: sqrt(t-7)

    Problem states to simplify (t-7)^1/2

    but we want to solve it so that it is not 0

    no, we want to manipulate it so that we have no zero in a denominator

    since the bottom cancels with the top; all thats left is a simple ordinary 0
