The sum of 7 cubed and the square root of 39 is approximately which value?

Explanation:
Think of this as adding a whole number to a small irrational. First, 7 cubed is exactly 343. The square root of 39 lies between 6 and 7 (since 6^2 = 36 and 7^2 = 49), and is about 6.244998, so the sum is roughly 343 + 6.245 ≈ 349.245. That makes the value closest to 349.245 among the given options.
