Tính giá trị biểu thức sau:
Bleft(18frac{1}{3}:sqrt{225}+8frac{2}{3}.sqrt{frac{49}{4}}right):left[left(12frac{1}{3}+8frac{6}{7}right)-frac{left(sqrt{7}right)^2}{left(3.sqrt{2}right)^2}right]:frac{1704}{445}
Cfrac{left(81,624:4frac{4}{3}-4,505right)^2+125frac{3}{4}}{left{left[left(frac{11}{25}right)^2:0,88+3,53right]^2-left(2,75right)^2right}:frac{13}{25}}

Tính giá trị biểu thức sau:
\(B=\left(18\frac{1}{3}:\sqrt{225}+8\frac{2}{3}.\sqrt{\frac{49}{4}}\right):\left[\left(12\frac{1}{3}+8\frac{6}{7}\right)-\frac{\left(\sqrt{7}\right)^2}{\left(3.\sqrt{2}\right)^2}\right]:\frac{1704}{445}\)
\(C=\frac{\left(81,624:4\frac{4}{3}-4,505\right)^2+125\frac{3}{4}}{\left\{\left[\left(\frac{11}{25}\right)^2:0,88+3,53\right]^2-\left(2,75\right)^2\right\}:\frac{13}{25}}\)

tính P = \(\dfrac{\left(81,624:4,8-4,505\right)^2+125.0,75}{\left\{\left[\left(0,44\right)^2:0,88+3,53\right]^2-\left(2,75\right)^2\right\}:0,52}\)
Tinh:
\(A=\dfrac{(13\dfrac{1}{4}-2\dfrac{5}{27}-10\dfrac{5}{6}).203\dfrac{1}{25}+46\dfrac{3}{4}}{(1\dfrac{3}{7}+\dfrac{10}{3}):\left(12\dfrac{1}{3}-14\dfrac{2}{7}\right)}\)
\(B=\dfrac{\left(81,624:4,8-4.505\right)^2+125.0,75}{\left\{\left[\left(0,44\right)^2:0,88+3,53\right]^2-\left(2,75\right)^2\right\}:0,52}\)
Rút gọn
a)\(\frac{25^{5^{ }}.5^{10}}{100^5}.\frac{4^6.9^5+6^9.120}{8^4.3^{12^{ }}-6^{11}}\)
b)\(\left(\frac{4}{9}+\frac{1}{3}\right)^2+\left(\frac{3}{4}\right)^2:\left(\frac{3}{4}\right)^2:\left(-\frac{2}{3}\right)^3\)
c) (273 : 33) : \(\left[\left(\frac{3}{5}\right)^{15}:\left(\frac{9}{25}\right)^5\right]\)
CÁC BẠN GIÚP MIH VỚI
\(\frac{0,8:\left(\frac{4}{5}.1,25\right)}{0,64-\frac{1}{25}}+\frac{\left(1,08-\frac{2}{25}\right):\frac{4}{7}}{\left(6\frac{5}{9}-3\frac{1}{4}\right).2\frac{2}{17}}+\left(1,2.0,5\right):\frac{4}{5}\)
\(\frac{\left(13\frac{1}{4}-2\frac{5}{27}-10\frac{5}{6}\right).230\frac{1}{25}+46\frac{3}{4}}{\left(1\frac{3}{7}+\frac{10}{3}\right):\left(12\frac{1}{3}-14\frac{2}{7}\right)}\)
a)\(\left(\frac{2}{3}+\frac{4}{5}+\frac{12}{7}\right)+\left(2^7.5^6-\frac{25^3}{\left(0.125\right)3}\right).\left(0.0001\right)^2\)
b) \(2\frac{1}{315}.\frac{1}{651}-\frac{1}{105}.3\frac{650}{651}-\frac{4}{315.651}+\frac{4}{105}\)
Tính giá trị các biểu thức:
\(\left[\left(\frac{4}{3}\right)^{-2}.\left(\frac{3}{4}\right)^4\right]\) \(:\left(\frac{3}{2}\right)^5\)
