Question

1) Calcule: a) √1 + √0 = b) √64 - √49 = c) 15 + √81 = d) 2 + √4/9 = e) -3 + √16 = f) -5 - √36 = g) 3√16 – 9 =

Answer 1

a) √1 + √0 = 1 + 0 = 1

b) √64 - √49 = 8 - 7 = 1

c) 15 + √81 = 15 + 9 = 24

d) 2 + √4/9 = 2 + 2/3 = 8/3

e) -3 + √16 = -3 + 4 = 1

f) -5 - √36 = -5 - 6 = -11

g) 3.√16 - 9 = 3.4 - 9 = 12 - 9 = 3

Answer 2

a)1+0=1
b)8-7=1
c)15+9=24
d)2+2/3= 6+2
              ____  = 8/3 
                  3
e)-3+4+1

f) - 5 - 6 = -11

g)3.4 - 9 = 12 - 9 = 3
