Question

(*là nhân,/ là phần, ^ là mũ)

Rút gọn:

P= 3^9*3^20*2^8/ 3^24*243*2^6

Q= 2^15*5^3*2^6*3^4/ 8*2^18*81*5

Answer 1

Q=2¹⁵.2⁶.5³.3⁴/2³.2¹⁸.3⁴.5

Q=2²¹.5³.3⁴/2²¹.3⁴.5

Q=25

Answer 2

\(P=\frac{3^9\cdot3^{20}\cdot2^8}{3^{24}\cdot243\cdot2^6}\)

\(P=\frac{3^{29}\cdot2^8}{3^{29}\cdot2^6}\)

\(P=2^2=4\)

\(Q=\frac{2^{15}\cdot5^3\cdot2^6\cdot3^4}{8\cdot2^{18}\cdot81\cdot5}\)

\(Q=\frac{2^{21}\cdot5^3\cdot3^4}{2^{21}\cdot3^4\cdot5}\)

\(Q=5^2=25\)

Answer 3

P=3^9*3^20*2^8/3^24*3^5*2^6

P=3^29*2^6*2^2/3^29*2^6

P=4
