B) 3⁴.3⁵ : 1/27

Answer 1

[Mai Lê Hiền Anh]

a) 4x32:(\(^{2^3}\)x\(\frac{1}{16}\))=\(^{2^2}\)x\(2^5\):[\(2^3\)x\(\left(\frac{1}{2}\right)^4\)] =\(2^7\):(\(2^3\)x\(2^{-4}\))=\(2^7\):\(2^{-1}\)=\(2^{7-\left(-1\right)}\)=\(2^8\)

b)\(3^4\)x\(3^5\):\(\frac{1}{27}\)=\(3^9\):\(\left(\frac{1}{3}\right)^3\)=\(3^9\):\(3^{-3}\)=\(3^{9-\left(-3\right)}\)=\(3^{12}\)

Answer 2

[Hồ Hoàng Trúc Vân]

a)\(4.32:\left(2^3.\frac{1}{16}\right)=2^2.2^5:\left(2^3.\frac{1}{2^4}\right)=2^7:\frac{1}{2}=2^7.2=2^8\)

b)\(3^4.3^5:\frac{1}{27}=3^9:\frac{1}{3^3}=3^9.3^3=3^{12}\)
