sai thấy mồ

sai

ok chưa

10^3+2x5+5^3/55=(2x5)^3+2x5^3+5^3/5x11

=2^3x5^3+2x5^3+5^3/5x11

=5^3x(2^3+2+1)/5x11

=5^3x11/5x11

=5^2=25

10^3+2x5+5^3/55=(2x5)^3+2x5^3+5^3/5x11

=2^3x5^3+2x5^3+5^3/5x11

=5^3x(2^3+2+1)/5x11

=5^3x11/5x11

=5^2=25

sai rồi

ta có:

25^15=(5^2)^15=5^30

8^10x3^30=(2^3)^10x3^30=2^30x3^30=(2x3)^30=6^30

vì 5>6 nên 5^30>6^30

vậy 25^15>8^10x3^30
