Question

Pls answer fast to ques numb 25,26,28,32 & 34 with explain

Answer 1

(25) Given {(-3}^2)^-1

                  = (3^2)^-1

                  = 1/3^2

                  = 1/9

                  = 0.111



(26) {(2/3)^2}^-1

      = 1/(2/3)^2

      = 1/(2^2/3^2)

      = 3^2/2^2

      = 9/4

      = 2.25.



(28)  {(0.2)^-2}^-2

         = 1/(0.2^-2)^2

         = 1/(0.2)^-4

         = 1/1/0.2^4

         = 0.2^4

         = 0.0016.


(32)  11/(2^-1 + 3^-2)

       = 11/(1/2 + 1/3^2)

       = 11/(11/18)

       = 11 * 18/11

       = 198/11

      = 18.


(34) 1/(0.2)^-2

      = 1/1/0.2^2

      = 0.2^2

      = 0.04.


Hope this helps!
