Answer 2

Answer:

16. interior angle = 108

    exterior angle = 72

    sum of interior angles = 540

17. length = 24 cm

    breadth = 16 cm

18.√276676 = 526

   √2766.76 = 52.6

   √27.6676 = 5.26

19. √2 = 1.41

20. √7³ x 5³ x $2^{6}$ = 7x5x8x√7x5 = 280√35

      √(-11)³ x $(-3)^{6}$ x $(-2)^{9}$ = (-11) x (-27) x (-16) x √(-11)x(-2) = -4752√22
