Answer 1

Răspuns:

1) a) 18

b)36

c)46

2) a)15,

b) 16,

c) 5*2*3^2=10*9=90

$3). \sqrt{ { - 2}^{2} \times 3 } = \sqrt{4 \times 3} = \sqrt{12} \\ 4 \sqrt{7} = \sqrt{ {4}^{2} \times 7} = \sqrt{16 \times 7} = \sqrt{112} \\ 2 \sqrt{9} = \sqrt{ {2}^{2} \times 9 } = \sqrt{4 \times 9} = \sqrt{36} = 6$
