Mathematical calculation problems, we come in to see When x = (3 radical 3) y = radical 2 Find the value of (X-Y) (x + y) (x ^ 2-xy + y ^ 2) (x ^ 2 + XY + y ^ 2) (sorry, the root number can't be typed)

X = 3 √ 3x & sup2; = 27y = √ 2Y & sup2; = 2 primitive = [(X-Y) (X & sup2; + XY + Y & sup2;)] [(x + y) (X & sup2; - XY + Y & sup2;)] = (X & sup3; - Y & sup3;) (X & sup3; + Y & sup3;) = x ^ 6-y ^ 6 = (X & sup2;) & sup3; - (Y & sup2;) & sup3; = 27 & sup3; - 2 & sup3; = 19675

If one third of a bottle of fruit juice is drunk, there will be 800 grams in a bottle. If one half of a bottle is drunk, there will be 700 grams in a bottle. How many grams in a bottle of fruit juice

800-700 = 100 (g)
1/2-1/3=3/6-2/6=1/6
100 / (1 / 6) = 600 (g)
600 * (1 / 2) = 300 (g)
700-300 = 400 (g)
(half + bottle) - (1 / 3 + bottle) = half - 1 / 3 = 100 (g), then calculate all the drinks, and then calculate half of the drinks, and then use half to reduce the bottle by half

There are 6 bottles of soy sauce. Each bottle contains the same amount of soy sauce. After 300 grams of each bottle is poured out, the remaining total weight is equal to the weight of the original 2 bottles. How many grams of soy sauce are there in each bottle?

Weight poured out: 300 * 6 = 1800 G
Number of bottles poured out: 6-2 = 4 bottles
Each bottle: 1800 / 4 = 450 G
Do you understand?
