a)√18
b)√8
c)√98
d)√48
e)√800
f√80

Answer 1

Respuesta:

$a) \sqrt{18} = \sqrt{9 \times 2} = \sqrt{9} \times \sqrt{2} = 3 \sqrt{2} \\ b) \sqrt{8} = \sqrt{4 \times 2} = \sqrt{4} \times \sqrt{2} = 2 \sqrt{2} \\ c) \sqrt{98} = \sqrt{49 \times 2} = \sqrt{49} \times \sqrt{2} = 7 \sqrt{2} \\ d) \sqrt{48} = \sqrt{16 \times 3} = \sqrt{16} \times \sqrt{3} = 4 \sqrt{3}$

$e) \sqrt{800} = \sqrt{400 \times 2} = \sqrt{400} \times \sqrt{2} = 20 \sqrt{2} \\ f) \sqrt{80} = \sqrt{16 \times 5} = \sqrt{16} \times \sqrt{5} = 4 \sqrt{5}$
