Hi, I got stucked while solving a differentiation question. Please consider helping me out. Find the derivative of sin^-1 (yx^2)

Need ! give step by step solutions on how to solve number one [tex]\frac{9-2\sqrt{3} }{12+\sqrt{3} }[/tex] number two [tex]x+4=\sqrt{13x-20}[/tex] number three (domain and range) [tex]f(x)=2\sqrt[3]{x} +1[/tex]

Two times a number plus three times another number equals 4. three times the first number plus four times the other number is 7. find the numbers

If the ratio of sum of the first m and n terms of an ap is m2 : n2 , show that the ratio of its mth and nth terms is (2m − 1) : (2n − 1).
