= 2^19 x (3^3)^3 + 3 x 5 x (2^2)^9 x (3^2)^4 / 2^9 x 3^9 x 2^10 + (2^2)^10 x 3^10
= 2^19 x 3^9 + 3^9 x 2^18 x 5 / 2^19 x 3^9+2^20 x 3^10
= 3^9 x 2^18 x (2+5) / 3^9 x 2^19 x (1 + 2 x 3)
= 3^9 x 2^18 x 7 / 3^9 x 2^19 x 7 = 1/2
k mk nha
Mn giúp tớ với ạ!
\(P=\frac{2^{19}\times27^3+15\times4^9\times9^4}{6^9\times2^{10}+12^{10}}\)
Tính
a)\(A=\frac{\left(3\times2^{20}+7\times2^{19}\right)\times52}{\left(13\times8^4\right)^2}\)
b)\(B=\frac{2^{19}\times27^3+15\times4^9\times9^4}{6^9\times2^{10}+12^{10}}\)
Các bạn ơi ,giúp mình với
Bài 1:Rút gọn
a)\(\frac{2^{19}\times27^3+15\times4^9\times9^4}{6^9\times2^{10}+12^{10}}\)
b)\(\frac{\left(\frac{-1}{2}\right)^3-\left(\frac{3}{4}\right)^3\times\left(-2\right)^2}{2\times\left(-1\right)^5+\left(\frac{3}{4}\right)^2-\frac{3}{8}}\)
c)\(\frac{45\times9^4-2\times6^4}{2^{19}\times3^8+6^8\times20}\)
Bài 2:Tìm x
a)\(5^x+5^{x+2}=650\)
b)\(3^{x-1}+5\times3=162\)
1 tính :
a)\(\frac{2^{11}\times9^2}{3^5\times16^2}\); b) \(\frac{9^3\times27^2}{6^2\times3^{10}}\); c) \(\frac{27^{15}\times5^3\times8^4}{25^2\times81^{11}\times2^{11}}\)
\(\dfrac{4^{10}\times9^6+3^{12}\times8^5}{6^{13}\times4-2^{16}\times3^{12}}\)
\(\dfrac{2^4\times2^6}{\left(2^5\right)^2}-\dfrac{2^5\times15^3}{6^3\times10^2}\)
\(\dfrac{\left(-2\right)^{10}\times3^{31}+2^{40}\times\left(-3\right)^6}{\left(-2\right)^{11}\times\left(-3\right)^{31}+2^{41}\times3^6}\)
giải chi tiết giúp mình nhé
thực hiện phép tính:\(A=\frac{2^{12}\times4^6\times9^2}{2^{12}\times3^6+8^4\times3^5}-\frac{5^{10}\times7^3-25^2\times49^2}{125^3\times7^3+5^9\times14^3}\)
Tính nhanh: \(E=\frac{4^9\times9^5+6^9\times2^6}{2^{10}\times3^8+6^8\times20}\)
\(\dfrac{4^{10}\times9^6+3^{12}\times8^5}{6^{13}\times4+2^{16}\times3^{12}}\)
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)\(\frac{4^6\times3^5-2^{12}\times3^6}{2^{12}\times9^3+8^4\times3^5}\)
