Ủng hộ nhé,tớ đang âm.

mấy câu này dễ

\(I=\frac{5.4^{15}.9^9-4.3^{20}.8^9}{5.2^9.6^{19}-7.2^{29}.27^6}=\frac{5.2^{30}.3^{27}-2^2.3^{20}.2^{27}}{5.2^9.2^{19}.3^{19}-7.2^{29}.3^{18}}\)

\(=\frac{5.2^{30}.3^{27}-3^{30}.2^{29}}{5.2^{28}.3^{19}-7.2^{29}.3^{18}}\)

\(=\frac{2^{29}.3^{27}.\left(5.2-3^3\right)}{2^{28}.3^{18}.\left(5.3-2.7\right)}\)

\(=\frac{2^{29}.3^{27}.-17}{2^{18}.3^{18}}\)

\(=\frac{2^9.3^9.-17}{1}\)

Ta có \(H=\frac{\left(3.4.2^{16}\right)}{11.2^{13}.4^{11}-16^9}\)

\(=\frac{3.4.2^{16}}{11.2^{13}.2^{22}-2^{36}}\)

\(=\frac{3.2^{18}}{11.2^{35}-2^{36}}\)

\(=\frac{3.2^{18}}{2^{35}.\left(11-2\right)}\)

\(=\frac{3.2^{18}}{2^{35}.3^2}\)

\(=\frac{1}{2^{17}.3}\)

Cảm ơn bạn nhé:)

\(\frac{27^3.4^5}{6^8}:\left(\frac{5^5.2^4}{10^4}:\frac{6^4}{2^6.3^4}\right)\)

\(=\frac{3^9.2^{10}}{6^8}:\left(5:\frac{1}{2^2}\right)\)\(=3.2^2:20=\frac{12}{20}=\frac{3}{5}\)

\(\frac{27^3.4^5}{6^8}:\left(\frac{5^5.2^4}{10^4}:\frac{6^4}{2^6.3^4}\right)\)

\(=\frac{\left(3^3\right)^3.\left(2^2\right)^5}{\left(3.2\right)^8}:\left(\frac{5^5.2^4}{\left(5.2\right)^4}:\frac{\left(2.3\right)^4}{2^6.3^4}\right)\)

\(=\frac{3^9.2^{10}}{3^8.2^8}:\left(\frac{5^5.2^4}{5^4.2^4}:\frac{2^4.3^4}{2^6.3^4}\right)\)

\(=3.2^2:\left(5:\frac{1}{2^2}\right)\)

\(=3.4:\left(5.4\right)\)

\(=12:20\)

\(=\frac{12}{20}=\frac{3}{5}\)

A = 2⁰ . 2¹ . 2² . 2³. 2⁴....2¹⁰⁰

   = 1 . 2¹ . 2² . 2³ . 2⁴ .... 2¹⁰⁰

   = 1 . 2^{1 + 2 + 3 + .... + 100}

Ta có : Số số hạng của dãy số 1 + 2 + 3 + .... + 100 là :

                      (100 - 1) : 1 + 1 = 100 ( số hạng )

Tổng của dãy số 1 + 2 +  3 + ... + 100 là :

                 (100 + 1) . 100 : 2 = 5050

Thay vào, ta được :

A = 1 . 2⁵⁰⁵⁰ = 2⁵⁰⁵⁰

Vậy A = 2⁵⁰⁵⁰

\(A=2^0.2^1.2^2.2^3.....2^{100}=2^1.2^2.2^3......2^{100}=2^{1+2+3+....+100}=2^{\left(1+100\right).\left(100-1+1\right):2}=2^{5050}\)

\(B=6^0.6^1.6^2.6^3.6^4......6^{600}=6^{1+2+3+4+...+600}=6^{\left(1+600\right).\left(600-1+1\right):2}=6^{180300}\)

\(C=7^0.7^1.7^2.7^3.7^4.....7^{700}=7^{0+1+2+3+4+...+700}=7^{\left(700+0\right).\left(700-0+1\right):2}=7^{245000}\)

\(D=8^1.8^2.8^3......8^{800}=8^{1+2+3+....+800}=8^{\left(800+1\right).\left(800-1+1\right):2}=8^{320400}\)

bài này không khó. Nhưng đánh máy để giải cho bạn thì thực sự khó

A) \(=\frac{\left(-1\right).2^{17}.5^6.3^{12}}{2^{16}.5^53^{13}}=\frac{10}{3}\)

B) Tương tự câu A bạn tự làm nha

Sửa câu A thành \(\frac{-10}{3}\)nha nãy viết vội quá

A) = \(\frac{\left(-1\right)\cdot2^{17}\cdot\left(5^2\right)^3\cdot\left(3^3\right)^4}{\left(2\cdot3\right)^{11}\cdot\left(2\cdot5\right)^5\cdot3^2}\)= \(\frac{\left(-1\right)\cdot2^{17}\cdot5^6\cdot3^{12}}{\left(2^{11}\cdot2^5\right)\cdot\left(3^{11}\cdot3^2\right)\cdot5^5}\)= \(\frac{\left(-1\right)\cdot2^{16}\cdot2\cdot5^5\cdot5\cdot3^{12}}{2^{16}\cdot3^{12}\cdot3\cdot5^5}\)

= \(\frac{\left(-1\right)\cdot2\cdot5}{3}=\frac{-10}{3}\)

B) = \(\frac{\left(3^2\right)^4\cdot\left(7^2\right)^3\cdot2^5}{\left(7\cdot3\right)^5\cdot3^4\cdot\left(2\cdot3\right)^3}\)= \(\frac{3^8\cdot7^6\cdot2^5}{7^5\cdot3^5\cdot3^4\cdot2^3\cdot3^3}\)= \(\frac{3^8\cdot7^5\cdot7\cdot2^3\cdot2^2}{7^5\cdot3^8\cdot3^4\cdot2^3}\)= \(\frac{7\cdot4}{3^4}\)= \(\frac{28}{81}\)

\(\frac{5.4^{15}.9^9-4.3^{20}.8^9}{5.2^9.6^{19}-7.2^{29}.27^6}\)=2

bạn lm hẳn ra ý

\(y=\frac{5\cdot4^{15}\cdot9^9-4\cdot3^{20}8^9}{5\cdot2^9\cdot6^{19}-7\cdot2^{29}\cdot27^6}\)

Tính(xin lỗi nha,ở trên mình ghi nhầm
