Answer 2

$\huge{\underline{\underline{\purple{♡Solution→}}}}$

1) → 4 × (-3) = -12

2) → 0 × 1/2 = 0

3)→ -3 + 2/3 = (-9+2)/3 = -11/3

4) → -6 × (-7/2) = 42/2 = 21

5) → 0-(-5) = 0+5 = 5

6) → 7 +(-9) = 7-9 = -2

7) → √(25/16) = 5/4

8) → 45/(-9) = -5

9) → $\frac{16}{4} - \frac{18}{4} = \frac{16 - 18}{4} = \frac{ - 2}{4} = - \frac{1}{2}$

10) → ${4}^{2} - {3}^{2} + {7}^{2} = 16 - 9 + 49 \\ = 7 + 49 = 56$

11) →$(p - 1)(p + 1) = {p}^{2} - 1$

12) →$( {p}^{2} + 1) \times 0 = 0$

13) → $\frac{1}{2} + \frac{5}{2} = \frac{6}{2} = 3$

14) → $\frac{68}{9} = 7.55$
