2^(10 : 64 x 16) = 2^[(10 x 16) : 64] = 2^(160 : 64) = 2^25
2^(10 x 8) = 2^80 3^(5 : 27) = 3^(5/27) 5^(2 x 125) = 5^250 6^(6 : 36) = 6^(1/6)
\(16^2:4^2\)
\(=\left(4^2\right)^2:4^2\)
\(=4^4:4^2\)
\(=4^{4-2}\)
\(=4^2\)

P/s: Mình chỉ hiểu ý bạn như này!
a,5 mũ 15
b,3 mũ 0=1
c,11 mũ 3
d,10 mũ 2
e,17 mũ 0=1
g,25 mũ 17
f,16 mũ 3
Chúc bạn học tốt,nhớ k cho mình nha
1) \(2^8.4.16.32.64.2=2^8.2^2.2^4.2^5.2^6.2=2^{8+2+4+5+6+1}=2^{26}\)
2) \(7.3^x-11=52\Rightarrow7.3^x=52+11=63\)
\(\Rightarrow3^x=63:7=9\Rightarrow3^x=3^2\Rightarrow x=2\)
\(4^{10\left(x+5\right)}=4^{12}\Rightarrow10\left(x+5\right)=12\)
\(\Rightarrow10x+50=12\Rightarrow10x=12-50=-38\)
\(\Rightarrow x=-38:10=-\dfrac{38}{10}=-\dfrac{19}{5}\)
\(7x-2x=6^{17}:6^{15}+2^8:2^6\)
\(\Rightarrow5x=6^2+2^2\Rightarrow5x=36+4=40\)
\(\Rightarrow x=40:5=8\)
\(3^{2x-1}=27\Rightarrow3^{2x-1}=3^3\Rightarrow2x-1=3\)
\(\Rightarrow2x=4\Rightarrow x=4:2=2\)
