\(A=\frac{100\times2^8\times5^{18}-2^{10}\times5^{19}\times15}{6\times2^8\times5^{19}+10\times2^8\times5^{18}}\)

Tính giá trị biểu thức sau:
\(\frac{45^{10}\times5^{20}}{75^{15}}\)

Trình bày rõ ràng giúp mình nha, cảm ơn!

1.Tính giá trị tuyệt đối:(hẹp me)

a)\(\frac{72^3\times54^2}{108^4}\)

b)\(\frac{3^{10}\times11+3^{10}\times5}{3^9\times2^4}\)

c)\(\left(1:\frac{1}{7}\right)^2[\left(2^2\right)^3:2^5]\times\frac{1}{49}\)

d)\(\frac{4^6\times3^5-2^{12}\times3^6}{2^{12}\times9^3+8^4\times3^5}\)

1 tính :

a)\(\frac{2^{11}\times9^2}{3^5\times16^2}\);  b)   \(\frac{9^3\times27^2}{6^2\times3^{10}}\);   c)  \(\frac{27^{15}\times5^3\times8^4}{25^2\times81^{11}\times2^{11}}\)

1.Tính giá trị tuyệt đối:(hẹp me)

a)\(\frac{72^3\times54^2}{108^4}\)

b)\(\frac{3^{10}\times11+3^{10}\times5}{3^9\times2^4}\)

c)\(\left(1:\frac{1}{7}\right)^2[\left(2^2\right)^3:2^5]\times\frac{1}{49}\)

d)\(\frac{4^6\times3^5-2^{12}\times3^6}{2^{12}\times9^3+8^4\times3^5}\)

thực hiện phép tính

A=\(\frac{3}{1\times5}+\frac{3}{5\times10}+....+\frac{3}{100\times105}\)

B=

\(\dfrac{5}{1\times3\times5}+\dfrac{5}{3\times5\times7}+...+\dfrac{5}{99\times101\times103}\)

\(a,\frac{3^6\times45^4-13^{15}\times5^{-9}}{27^4\times25^3+45^6}\)                                 

\(b,\frac{\left(\frac{2}{5}\right)^7\times5^7+\left(\frac{9}{4}\right)^3\div\left(\frac{3}{16}\right)^3}{2^7\times5^2+512}\)

Rút gọn hợp lí

a) \(M=\frac{131\times145+100}{45-132\times145}\)

b)\(N=\frac{49^6\times5-7^{11}}{\left(-7\right)^{10}\times5+2\times49^5}\)
