\(\sqrt{1}+\sqrt{49}=1+7=8\)
\(\sqrt{25}+\sqrt{100}=5+10=15\)
$\sqrt{1}+\sqrt{49}$=1 + 7 = 8
$\sqrt{25}+\sqrt{100}$= 5 + 10 = 15 nha
a,\(\sqrt{49-\sqrt{4+\sqrt{25}}}\)
b,\(\left(\sqrt{100-\sqrt{1}}\right):\sqrt{\left(-3\right)^2}\)
c,\(\sqrt{16+9-\sqrt{25-9}}\)
d,\(\sqrt{\left(-7\right)^2-\sqrt{1^{40}}.\sqrt{16}}\)
Tính
A=\(\sqrt{0,36}-\left(\sqrt{25}-\sqrt{49}:\sqrt{4}\right).\sqrt{0,4}-\sqrt{10}^2\)
\(\sqrt{9}\)=?
\(\sqrt{25}\)=?
\(\sqrt{49}\)=?
\(\sqrt{100}\)=?
\(Cho\)\(x=\left(1+\frac{1}{\sqrt{1}}\right)+\left(1+\frac{1}{\sqrt{9}}\right)+\left(\frac{1}{\sqrt{25}}\right)+\left(1+\frac{1}{\sqrt{49}}\right)+\left(1+\frac{1}{\sqrt{81}}\right)\)
\(y=\left(1+\frac{1}{\sqrt{4}}\right)+\left(1+\frac{1}{\sqrt{16}}\right)+\left(1+\frac{1}{\sqrt{36}}\right)+\left(1+\frac{1}{\sqrt{64}}\right)+\left(1+\frac{1}{\sqrt{100}}\right)\)
Tính x.y
Mn ơi, giúp mk nha, mai mk nộp òi!
Tính:\(\left(-\frac{1}{3}+\frac{5}{6}\right)^2-\frac{-\sqrt{25^2}-\sqrt{49^2}}{\sqrt{36^2+\sqrt{38^2}}}\)
Nhớ giải cho thật kĩ!!
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.\(\sqrt{\frac{4}{25}}\)
\(\sqrt{36}+\sqrt{10000}-\sqrt{4}+\sqrt{25}-\sqrt{36}+\sqrt{49}-\sqrt{10000000000}\)
Tính \(\sqrt{81=}\)
\(\sqrt{0,64=}\) \(\sqrt{\frac{49}{100}=}\)
\(\sqrt{8100=}\) \(\sqrt{100=}\)
\(\sqrt{0,01=}\) \(\sqrt{\frac{4}{25}=}\) \(\sqrt{\frac{0,09}{121}=}\)
Ng các bạn giúp mik xin cảm ơn
\(Tính:\)
\(a.\sqrt{25}-\sqrt{16}+\sqrt{1}\)
\(b.\sqrt{\frac{4}{9}}+\sqrt{\frac{25}{4}}+\sqrt{\left(-3\right)^4}\)
\(c.\frac{7}{5}+\sqrt{49}+\sqrt{\left(-3\right)^2}\)
