Suppose f(x)greater than0 for all x and integral from 0 to 4 f left parenthesis x right parenthesis dxequals22. let r be the region in the first quadrant bounded by the coordinates axes, yequalsf(xsquared), and xequals2. find the volume of the solid generated by revolving r around the y-axis.

C. expression because any expression or equation may contain more than one variable

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
