Q2-Determine the value of each of the following expressions: a. ceil(36.1) d. pow(3.2, 2) g. pow(2.5, 3) j. fabs(11.8) b. pow(3.0, 4.0)/abs(-9) e. abs(-10) h. sqrt(38.2 c. fabs(-5.8) f. sqrt(36.0) i.floor(25.95) Q3-Consider the following statements: double num1, num2, num3; int int1, int2, int3; int value; num1 = 5.0; num2 = 6.0; num3 = 3.0; int1 = 4; int2 = 7; int3 = 8; and the function prototype: double cube(double a, double b, double c); Which of the following statements are valid? If they are invalid, explain why. a. value = cube (num1, 15.0, num3); b. cout
