*note:- here digits in bracket are exponent or power.

  • Law of Product: a^m × a^n = a^m+n
  • Law of Quotient: a^m/a^n = a^m-n
  • Law of Negative Exponent: a^-m = 1/a^m
  • Law of Power of a Power: (a^m)^n = a^mn
  • Law of Power of a Quotient: (a/b)^m = a^m/b^m

Given Expression :- (2[2].2[-4])[3]/2[-3] its equivalent value is:-

we can write it as (2^2 * 2^-4)^3/ 2^-3    (apply law of product)

      = (2^2+(-4))^3 / 2^-3

      =(2^-2)^3 */2^-3                            (apply law of power of power)

      = 2^-6 /2^-3                                (apply law of product)

      =2^(-6-(-3))                                  (apply law of quotient)

      =2^(-6+3)

       =2^-3                                    (apply law of negative Exponent)

        =1/ 2^3

       =1/8 (Answer)
