Answer 2

Given :-

1/2x ³ × (-10x) × 1/5x²

x = 1

To find :-

Product of given terms.

To prove :-

The answer = 1

Solution :-

½x³ × (-10)x + ⅕x²

½ (-10)(x³) (x) × ⅕x²

(-5)x⁴ × ⅕x²

⅕(-5) (x⁴) (x²)

-x⁶

Now , put x = 1

½ (1)³ × (-10) (1) + ⅕ (1)² = -1⁶

½ × -10 × ⅕ = -1

⅒/10 × -10 = -1

- 1 = -1$\:$
