a: \(A=8^2\cdot32^4=2^6\cdot2^{20}=2^{26}\)

a: \(A=\left(2^3\right)^2\cdot\left(2^5\right)^4=2^6\cdot2^{20}=2^{26}\)
b: \(=\left(3^3\right)^3\cdot\left(3^2\right)^4\cdot3^5=3^9\cdot3^8\cdot3^5=3^{22}\)
\(A=8^2.32^4=\left(2^3\right)^2.\left(2^5\right)^4=2^6.2^{20}=2^{26}\)
\(B=27^3.9^4.243=\left(3^3\right)^3.\left(3^2\right)^4.3^5=3^9.3^8.3^5=3^{22}\)

a, \(3^4\)
b, \(8^7:8^2\)
c, \(x^3.x^2.x\)
d, \(4^n.4^2\)
e, \(3^{k+2}:3^k\)
a, 3^4
b,8^7:8^2=8^5
c, x^3.x^2.x=x^6
d,4^n.4^2=4^(n+2)
e, 3^k+2:3^k
=3^k.(1+2)
=3^k.3
=3^(k+10
Mấy bài này đẽ ẹc mà !!!

\(8^4.16^5.32=2^{3.4}.2^{4.5}.2^5=2^{12}.2^{20}.2^5=2^{12+20+5}=2^{37}\)
84.165.32=24.3.24.5.25= 212+20+5=227
( nhớ tick đúng cho mình nha)

\(x^4\cdot x^7\cdot...\cdot x^{100}\)
\(=x^{4+7+...+100}\)
\(=x^{52\cdot33}=x^{1716}\)
\(x^1\cdot x^2\cdot x^3\cdot...\cdot x^{2006}\)
Ta có : \(x^1\cdot x^2=x^{1+2}=x^3\)
Tương tự : \(x^1\cdot x^2\cdot x^3=x^{1+2+3}=x^6\)
Áp dụng vào bài toán :
\(x^1\cdot x^2\cdot x^3\cdot...\cdot x^{2006}=x^{1+2+3+...+2006}\)
\(\Rightarrow x^{1+2+3+...+2006}=x^{2013021}\)

Nhân 16 mũ mấy vậy bạn? ( Ko đử dữ liệu để trả lời )

@Kawasumi Rin
\(4^2\times8^2\)
\(=\left(2^2\right)^2\times\left(2^3\right)^2\)
\(=2^4\times2^6=2^{10}\)
42x82=(4x8)2
=322
