Rewrite the following statements using set notation : (i) a is an element of set A. (ii) b is not a element of A. A is a empty set and B is a nonemept

Correct Answer - B `(b)` `{:("Partitioning",,"Number of ways"),(4"members",,1),(1+3"members",,(4!)/(1!3!)=4),(2+2"members",,(4!)/((2!)^(2)2!)=3),(1+1+2"members",,(4!)/((1!)^(2)2!2!)=6),(1+1+1+1"members",,(4!)/((1!)^(4)4!)=1),("Total",,15"ways"):}`

To perform addition operation, first the numbers are written in such a way that they have the same exponent. The coefficients are then added. (5.55 × 104) + (6.95 × 103) =...

(1.77 × 102) + (2.23 × 103)  = (0.177 × 102) + (2.23 × 103)  = (0.177 + 2.23) × 103  = 2.407 × 103

(5.6 × 105) × (6.9 × 108)  = (5.6 × 6.9) (105+8) = 38.64 × 1013 = 3.864 × 1014

(9.8 × 10-2) × (2.5 × 10-6)  = (9.8 × 2.5) (10-2+(-6)) = (9.8 × 2.5) × (102-6) = 24.5 × 10-8 = 2.45 × 10-7

We need to hold fast to constitutional methods.
