Tính
\(A=\frac{0,4.10^{-8}.4.6,28}{3,14.\left(2.10^{-5}\right)^2}\) ; \(B=\frac{4^5.9^4-2.6^9}{2^{10}.3^8+6^8.20}\) ; \(C=\frac{8^{20}+4^{20}}{4^{25}+64^5}\)
\(\dfrac{4^5.9^4}{8^3.27^3}\);\(\dfrac{4^{20}.3^{35}}{2^{37}.27^{12}}\)\(;\dfrac{5^4.20^4}{25^5.4^5};\dfrac{2^{15}.9^4}{6^6.8^3}\)
1) tìm x biết
\(x^{10}=25x^8\)
2) tính M
\(\frac{8^{20}+4^{20}}{4^{25}+64^5}\)
Thực hiện phép tính:
\(\frac{8^{20}+4^{20}}{4^{25}+64^5}\)
1/Tìm x :
a) x10 = 25.x8
b)( 2x + 32 ) =\(\frac{9}{121}\)
2/ Chứng minh rằng : 106 - 57 chia hết cho 59
3/ Rút gọn : \(\frac{8^{20}+4^{20}}{4^{25}+64^5}\)
\(M=\frac{8^{20}+4^{20}}{4^{25}+64^5}\)
\(M=\frac{8^{20}+4^{20}}{4^{25}+64^5}\)
tính :
M = \(\frac{8^{20}+4^{20}}{4^{25}+64^5}\)
các bạn giúp mk giải kĩ vào nhé
Bài 1.Tính : M=\(\frac{8^{20}+4^{20}}{4^{25}+64^5}\)
Bài 2.Tính x,biết :
a) \((x^4)^2=\frac{x^{12}}{x^5}(x\ne0)\) b)\(x^{10}=25x^8\)
Baì 3.Tĩnh x,biết:
a) \(\left(2x+3\right)^2=\frac{9}{121}\) b)\(\left(3x-1\right)^3=-\frac{8}{27}\)
