b) - 64
c) 100
d) - 49
e)400
f)-900
g)-2500
h) 144​

Answer 1

Resposta:

a)

\sqrt{36} = \sqrt{6 {}^{2} } = 636=62=6

b)

- \sqrt{64} = - \sqrt{8 {}^{2} } = - 8−64=−82=−8

c)

\sqrt{100} = \sqrt{10 {}^{2} } = 10100=102=10

d)

- \sqrt{49} = - \sqrt{7 {}^{2} } = - 7−49=−72=−7

e)

\sqrt{400} = \sqrt{20 {}^{2} } = 20400=202=20

f)

- \sqrt{900} = - \sqrt{30 {}^{2} } = - 30−900=−302=−30

g)

- \sqrt{2500} = - \sqrt{50 {}^{2} } = - 50−2500=−502=−50

h)

\sqrt{144} = \sqrt{12 {}^{2} } = 12144=122=12
