Answer:
A: 20
B: 2
C: 3
D: -4
Explanation:
5 I 3-7 I
First we have to solve the absolute value of 3-7 which is 4 after that we have to multiply 5 by 4 leading us to get an answer of 20
-18+4 is -14 and the absolute value of -14 is 14 and so when you subtract 16 and 14 you get 2
For question 3 or C 3sqrt means raised to the 1/3 power and since 27 is just 3^3 we can do 3^(1/3*3) or 3^1 which is just 3
For the last question we can use the same principal -64 is basically just
-4*-4*-4 which can be written as -4^3 and 3sqrt is just raising it to the 1/3 power so -4^(1/3*3) is just -4
