Question

So sánh

\(A=\frac{8^9+12}{8^9+7}\)

\(B=\frac{8^{10}+4}{8^{10}-1}\)

Answer 1

A=1+\(\frac{5}{8^9+7}\)

B=1+\(\frac{5}{8^{10}-1}\)

vi \(\frac{5}{8^9+7}\)->\(\frac{5}{8^{10}-1}\)

=>a>b

 

Answer 2

A = 1 + 5/8⁹ + 7

B = 1 + 5/8^{10 - 1}

Vì 5/8⁹ + 7 -> 5/8¹⁰ - 1 

=> A > B

Answer 3

A> b nha

đúng 100%

ai tk tớ,tớ tk lại

Answer 4

A=1+5/8^9+7

B=1+5/8^10-1

Vi.   5/8^9+7>5/8^10-1

suy ra A>B
