Answer 2

• We have to evaluate the above expression by using the given data.

              Given data:- $x=-2.$

              To find:- Value of above expression $4x^{3} .$

              Solution:-

• To solve the above equation we will follow the BODMAS rule.

• BODMAS is an order of mathematic operations.

• BODMAS rule is to be followed while solving expressions in mathematics.

       It stands for,

           B= bracket

           O= order of power or rules

           D= division

           M= multiplication

           A= addition

           S= subtraction

    Now put the value a and b in the given equation we get,

          $4x^{3} \\=>4\times(-2)^{3} \\=>4\times-8\\=>-32.$

   Hence we will get he value $4x^{3} =-32.$
