Answer 1

In solving a quadratic equation, one of the values of the variable x is 233.356. The solution rounded to two significant figures is 230.

Explanation:

“Two significant figures” means keep the first two non‑zero digits and round the rest. 233.356 = 2.33356 × 10²; keeping two significant figures gives 2.3 × 10² = 230.
