Question

find lim (21-y)^5/6
y→-6

Answer 1

Is that \[\lim_{y\rightarrow-6}(21-y)^{5/6}\]?

Answer 2

yes

Answer 3

sorry i meant 5/3

Answer 4

If you set y = -6 in the formula, you get:\[27^{\frac{ 5 }{ 3 }}\]This number can be simplified further, because 27 is itself a power of 3, so the final answer is a nice integer.
