The value of (√9²+12²) + (-3)² - (-1 + 2 + 3)³ - ³√-125 is _____?
- +35
- -35
- -10
- None of these
Explanation
Let's break it down step by step:
1. (√9²+12²) = √(81+144) = √225 = 15
2. (-3)² = 9
3. 15 + 9 = 24
4. (-1 + 2 + 3) = 4, and 4³ = 64
5. 24 - 64 = -40
6. ³√-125 = -5 (since (-5)³ = -125)
7. -40 - (-5) = -40 + 5 = -35
