0.625*0.625.0.625{共9个0.625}*8*8.*8{共10个8}*2*2.2{共9个2}0.625*0.625.0.625{共9个0.625}*8*8.*8{共10个8}*2*2.2

0.625*0.625.0.625{共9个0.625}*8*8.*8{共10个8}*2*2.2{共9个2}
0.625*0.625.0.625{共9个0.625}*8*8.*8{共10个8}*2*2.2{共9个2}

0.625*0.625.0.625{共9个0.625}*8*8.*8{共10个8}*2*2.2{共9个2}
0.625 = 5/8
(5/8)^9 * 8^10 * 2^9
= 5^9 * ((1/8)^9 * 8^9) * 2^3 * 2^9
= 5^9 * 2^12
= (5*2)^9 * 2^3
= 8,000,000,000

。。。好难

二楼的手真高啊,厉害
