1) One millimeter = .1 centimeters, so you are adding (43 + 0.62) cm, and you are correct in assuming the result will be 43.62 cm.
2) I assume you want (3/4)^3*(4/5)^2. You could just enter this in a calculator, but in this specific case there is a simplification. (3/4)^3 = 3^3/4^3, and (4/5)^2 = 4^2/5^2. So the answer is (3^3*4^2)/(4^3*5^2). The 4^2 term cancels and you are left with 3^3/(4*5^2). 3^3 = 3*3*3 = 27. 4*5^2 = 4*25 = 100, so the answer is 27/100 or 0.27.
