question no 1 answer please....

Answer 1

Option (B) - 2.7

Given (3)^1/3 + 1/2 + 5/4 - 3/4 * (0.3)^1/3 * (0.9)^4/3 - 2/3.

       =   (3)^1/2 + 1/2 + 1/3  * (0.3)^1/3   * (0.9)^4/3 - 2/3

       =   (3)^1/2 + 1/2 + 1/3 * (0.3)^1/3 * (0.9)^2/3

       =   3 * (3)^1/3 * (0.3)^1/3 * (0.9)^2/3

 We know that a^mb^m = (ab)^m

      = 3 * 0.9^2.3 * (3 * 0.3)^1/3

     = 3 * 0.9^1/3 * (0.9)^2/3

     = 3 * 0.9^1/3 + 2/3

     = 3 * 0.9^1

     = 3 * 0.9

     = 2.7.


Hope this helps!
