How do you answer 6 (2x7 58)?

The expression "6 (2x7 58)" seems to contain a multiplication and possibly a missing operator. Assuming you meant to multiply 2 by 7 first, and then multiply that result by 6, you would calculate it as follows: 2 x 7 = 14, then 6 x 14 = 84. If "58" is intended to be added, the expression would need clarification. Please provide more details for an accurate solution.
