Answer: Let’s break down the given mathematical expression step by step to understand how to solve it.

  1. Calculate the Cube Roots:

    • First, we need to find the cube root of 1331. The cube root of a number ( n ) is a number ( a ) such that ( a^3 = n ).
    • ( 11^3 = 1331 ) therefore, the cube root of 1331 is 11.
    • Then, find the cube root of 343. Similarly, the cube root of a number ( n ) is ( a ) where ( a^3 = n ).
    • ( 7^3 = 343 ) so, the cube root of 343 is 7.

  2. Perform the Multiplication:

    • Multiply the results from the previous step: ( 11 \times 7 = 77 ).

  3. Perform the Division:

    • Divide the multiplication result by 49: ( \frac{77}{49} ).
    • Simplifying this, we have: ( \frac{77}{49} = \frac{77}{49} = 1.57142857 ) or simplifying further, ( \frac{77}{49} = \frac{49 \times 1 + 28}{49} = 1 + \frac{28}{49} = 1 + \frac{4}{7} = 1.57142857 ).

  4. Subtract 28:

    • From the result of the division, subtract 28: ( 1.57142857 - 28 = -26.42857143 ).

Therefore, the expression root 1331 * 343 divide 49 - 28 results in (-26.42857143).

In summary, the problem primarily involved calculating cube roots and performing arithmetic operations following the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction).
