Open in App
Solution

Convert the square root to its exponential form and then use the power rule.
y=x=x12
Now bring the power of 12 down as a coefficient and then subtract 1 from the current power of 12. Evaluate the fractions and simplify. Manipulate exponents from negative to positive.
y=12x(121)=12x(1222)=12x(12)=12x12=12x
