1) √16 + 9 = 4 + 9 = 13

2) √16 + √9 = 4 + 3 = 7

3) √36 - √49 = 6 - 7 = -1

4) √36 × √49 = 6 × 7 = 42

5) 5√4 - √25 = 5*2 - 5 = 10 - 5 =5

6) √0.81 + √0.01 = 0.9 + 0.1 = 1

7) 1/3√0.09 - 2 = 1/3*0.3 - 2 = 0.1 - 2 = -1.9

8) -2√0.16 + 0.7 = -2*0.4 + 0.7 = -0.8 + 0.7 = -0,1

9) (√13)² - 3×(√8)² = 13 - 3*8 = 13 - 24 = -11
