Answer:
(2+3)(2−3)(5+2)(5−2)=>(22−(3)2)(52−(22))=>(4−3)(25−2)=>(1)(23)=>23

The machine gun and the tank were new technologies that influenced WW1 the most. The machine gun lengthened the war and forced it to become a trench war. The bullets in a machine gun could shoot 500 bullets per minute therefor making it much more difficult for the rivalry county to fight back.
Remember
∛(ab)=(∛a)(∛b)
also
i¹=i
i²=-1
i³=-i
i⁴=1
so
∛-2i=(∛2)(∛-i)=(∛2)(i)=i∛2
2/5 ÷ x = 4/5
multiply both sides by x to get it out of the denominator.
2/5 = 4/5x
now divide each side by 4/5 to get x by itself.
2/5 ÷ 4/5 = x
divide fractions by multiplying the reciprocal of the divisor.
2/5x × 5/4 = x
10/20 = x
1/2 = x
So 2/5 divided by 1/2 =4/5
The answer is 13/85. You could find out the answer by doing the reprical multiplication.
