Question

tính:

a. \(\sqrt{81}\)

b.\(\sqrt{8100}\)

c.\(\sqrt{64}\)

d.\(\sqrt{25}\)

e.\(\sqrt{0,64}\)

f.\(\sqrt{10000}\)

g.\(\sqrt{0,01}\)

h.\(\sqrt{\frac{49}{100}}\)

i.\(\sqrt{\frac{0,09}{121}}\)

j.\(\sqrt{\frac{4}{25}}\)

Answer 1

\(a,\sqrt{81}=9\)

\(b.\sqrt{8100}=90\)

\(c,\sqrt{64}=8\)

\(d,\sqrt{25}=5\)

\(e,\sqrt{0,64}=0,8\)

\(f,\sqrt{10000}=100\)

\(g,\sqrt{0,01}=0,1\)

\(h,\sqrt{\frac{49}{100}}=\frac{7}{10}\)

\(i,\sqrt{\frac{0,09}{121}}=\frac{0,3}{11}\)

\(j,\sqrt{\frac{4}{25}}=\frac{2}{5}\)
