\(=\dfrac{\left(0.125\cdot2.4\right)^5}{\left(-0.3\cdot0.01\right)^3\cdot\left(-0.3\right)^2}=\dfrac{0.3^5}{0.3^2\cdot\left(-0.003\right)^3}=\dfrac{0.3^3}{-0.003^3}=-1000000\)
Tính giá trị biểu thức:
\(\frac{\left(0,125\right)^5.\left(2,4\right)^5}{\left(-0,3\right)^5.\left(0,01\right)^3}\)
Tính giá trị của biểu thức sau.
\(\frac{\left(0,125\right)^5.\left(2,4\right)^5}{\left(-0,3\right)^5.\left(0,01\right)^3}\)
\(\frac{\left(-0,125\right)^5.\left(2,4\right)^5}{\left(-0.3\right)^5.\left(0.01\right)^3}\) giải giúp mk nhoa
Tính:

b)\(0,4\left(3\right)+0,6\left(2\right)-2\frac{1}{2}.\left[\left(\frac{1}{2}+\frac{1}{3}:0,5\left(8\right)\right)\right]:\frac{50}{53}\)
c)\(\frac{0,375-0,3+\frac{3}{11}+\frac{3}{12}}{0,625-0,5+\frac{5}{11}+\frac{5}{12}}\)
Thực hiện phép tính :
\(\left\{\left[\left(2\sqrt{2}\right)^2+2,4\right]\left[5,25:\left(\sqrt{7}\right)^2\right]\right\}:\left\{\left[2\frac{1}{7}+\frac{\left(\sqrt{5}\right)^2}{7}\right]:\left[2^2:\frac{\left(2\sqrt{2}\right)^2}{\sqrt{81}}\right]\right\}\)
Ai làm đc bài này thì giỏi quá
Tính :
A = \(\left(1-\frac{2}{3}+\frac{4}{3}\right)-\left(\frac{4}{5}-1\right)+\left(\frac{7}{5}+2\right)\)
B = \(\left(-3+\frac{3}{4}-\frac{1}{3}\right):\left(5+\frac{2}{5}-\frac{2}{3}\right)\)
C = \(\left(\frac{3}{5}-\frac{4}{5}\right).\left(\frac{2}{7}-\frac{3}{14}\right)-\left(\frac{5}{9}-\frac{7}{27}\right).\left(1-\frac{3}{5}\right)+\left(1-\frac{11}{12}\right).\left(1-\frac{11}{12}\right)\)
Thực hiện phép tính:
a,\(25\frac{3}{5}:\left(\frac{-2}{3}\right)-15\frac{3}{5}:\left(\frac{-2}{3}\right)\)
b,\(9.\left(\frac{-2}{3}\right)^3+\frac{1}{2}:5\)
c,\(\left[10\left(\frac{-1}{5}\right)^2+5\left(\frac{-1}{5}\right)+1\right]:\left(\frac{-1}{5}-1\right)\)
Tính :
\(a) 27^{3}:3^{2}\)
\(b) \left ( \frac{3}{5} \right )^{15}:\left ( \frac{9}{25} \right )^{5} \)
\(c) 5-\left ( -\frac{5}{11} \right )^{0}+\left ( \frac{1}{3} \right )^{2}:3 \)
\(d) 2^{3}+3.\left ( \frac{1}{2} \right )^{0}+\left[ {\left ( -2 \right )^{2}:\frac{1}{2}} \right].8 \)
Các bạn giúp mình với nhé, cảm ơn các bạn !
Tính :
\(a,\left(\frac{4}{9}+\frac{1}{3}\right)^2\)
\(b,\left(\frac{1}{2}-\frac{3}{5}\right)^3\)
\(c,\left(\frac{-1}{5}\right)^5.\left(\frac{-6}{5}\right)^4\)
\(d,\left(\frac{3}{4}\right)^3:\left(\frac{3}{4}\right)^2:\left(\frac{-2}{5}\right)^3\)
