HCF= highest common factor
LCM= least common multiple
She need 3 bags since the area of the triangle is base x height /2
Area 20*6=120
120/2=60
60/20= 3 since each bag covers 20m^2
10 n = C
Finding the total would simply be multiplying the cost of the tickets by number of students.
the answer is 16
8^(4/3) can be written in different ways. You can first simplify it by breaking the exponents down into 1/3 and 4. You can write it as (8^1/3)^4 (it still means the same thing). When you raise something to the one over something fraction, the denominator tells you what the root is. Because it says 1/3, it means that you're finding the cube root of something. So you can rewrite it as (3√8)^4 (the three should be sitting on top of the sign to signify that it's cube root). You then just solve from there. The cube root of 8 is 2 (2*2*2=8) so it'll simplify to (2)^4. You then solve it from there and get 16 as your answer (2*2*2*2=16).
