`-5-40+20+2times3`

Is [(-5)times2)]times3 = (-5)times[(2times3)] ?

Solve : (2/3)^4 times ( 3/2 )^5 times (5/3 )^-2 times ( 3/5 )^-3

Evaluate : [ (2/5 )^2 ]^3 times ( 5/4 )^3 times (1/5 ) times ( 2/3 )

Evaluate : (( 5 )^3 times ( 3 )^3 )/ ( ( 2 )^5 times ( 2 )^4 times ( 7^5 )^3)

Evaluate : 5/7 times 7/2 + 3/2 times ( -2/3 ) - 2/5 times 5/2

The smallest among 5^(20),4^(30),3^(40) and 2^(50) is
