Verify `[(-2/3)+4/5]+((-1)/(-7))=(-2/3)+[4/5+((-1)/(-7))]`

Verify that: (2)/(3)xx(-(4)/(5)+(-(3)/(7)))=(2)/(3)xx(-(4)/(5))+(2)/(3)xx(-(3)/(7))

5(1)/(7)times3(2)/(4)

"(5)/(-7)+2(1)/(3)+4(2)/(5)

" (iii) ((-2)/(5)+(4)/(7))+((-2)/(5)) ( iv )(3)/(4)+(7)/(6)+((-5)/(4))+(1)/(2)

1+(3)/(2+(1)/(4+(5)/(7)))

(7)/(8)-:(7(1)/(2)-5(1)/(6)-:2(3)/(4))+4(1)/(2)

Verify the following: (i) ((3)/(4)+(-2)/(5))+(-7)/(10)=(3)/(4)+((-2)/(5)+(-7)/(10)) (ii) ((-7)/(11)+(2)/(-5))+(-13)/(22)=(-7)/(11)+((2)/(-5)+(-13)/(22)) (iii) -1+((-2)/(3)+(-3)/(4))=(-1+(-2)/(3))+(-3)/(4)

If A=[(2)/(3)1(5)/(3)(1)/(3)(2)/(3)(4)/(3)(7)/(3)2(2)/(3)] and B=[(2)/(3)(2)/(5)1(1)/(5)(2)/(5)(4)/(5)(4)/(5)(7)/(3)(6)/(5)(2)/(5)], then compute 3A_(-)=5B

((-4)/(3))times(1)/(2)+((-4)/(3))times((-7)/(5))

The greatest of the numbers 2(1)/(2),3^((1)/(3)),4^((1)/(4)),5^((1)/(5)),6^((1)/(6)) and 7^((1)/(7)) is
