Question

please answer dear brainy friends so urgent ​

Answer 1

Answer:

(a)( 4^-1/2 ×  2^1/2 × 2  )/ ( 8   × 8^-1/2  )

   = (√8 ×√2×2 ) / (√4 ×8)

   = (2√2×2√2 ) /(2×8)

    =8/16

   = 1/2 (answer)

(b) (48^-2  × 64^1/2  ) / 24^ -1

     = (√64×24  )/ 48²

     =8×24/48²

     =192/48²

     =1/12 (answer)

Answer 2

Answer:

(a) 1/√4 × √2 ×2

           8 × 1/√8

= 1/2 ×√2 × 2

      8 × 1/2√2

= √2

  4/√2

= √2 × √2/4

= 2/4

= 1/2

(b) 1/48² × √64

           1/24

= 1/2034 × 8

        1/24

=  288 × 24/1

=   6912

Hope its helpful!!!!
