bạn team ff và team fa lạc đề rồi

a) 16^5

b)18^6

mk chỉ giải đc thế thui

các bạn oi 16 mũ 6 : 4 mũ 2 viết dưới dạng lũy thừa bằng bao nhiêu thế

bn ơi viết kiểu này mik hơi khó hiểu!

A = 8² . 32⁴ = 64 . 1048576 = 67108864 = 8192²

\(A=8^2.32^4=\left(2^3\right)^2.\left(2^5\right)^4=2^6.2^{20}=2^{26}\)

\(B=27^3.9^4.243=\left(3^3\right)^3.\left(3^2\right)^4.3^5=3^9.3^8.3^5=3^{22}\)
