The 3 expressions that use each of the numbers 2,3,6, and 8 only once and any operations are 3 x 8 + 6 – 2 = 28 and 3 + 8 – 6 x 2 = - 1 and 3 – 8 x 6 + 2 = - 43
Solution:
Given that , we have to write at least 3 expressions that use each of the numbers 2,3,6, and 8 only once and any operations and grouping symbols (addition, subtraction, multiplication, division, and parentheses).
Each expression should have a different value, with one being equal to 28.
Now, let the expressions be
[tex]\begin{array}{l}{3 \times 8+6-2 = 28} \\ {3+8-6 \times 2 = -1} \\ {3-8 \times 6+2 = -43}\end{array}[/tex]
Hence, the three expressions are 3 x 8 + 6 – 2 = 28 and 3 + 8 – 6 x 2 = - 1 and 3 – 8 x 6 + 2 = - 43
