〖1/1算式〗
作业：求算式 (1.2^1)+(1.2^2)+(1.2^3)+(1.2^4)+(1.2^5)+(1.2^6)+(1.2^7)+(1.2^8) 的值.
题型：数学计算
解:
(1.2^1)+(1.2^2)+(1.2^3)+(1.2^4)+(1.2^5)+(1.2^6)+(1.2^7)+(1.2^8)
=1.2+(1.2^2)+(1.2^3)+(1.2^4)+(1.2^5)+(1.2^6)+(1.2^7)+(1.2^8)
=1.2+1.44+(1.2^3)+(1.2^4)+(1.2^5)+(1.2^6)+(1.2^7)+(1.2^8)
=1.2+1.44+1.728+(1.2^4)+(1.2^5)+(1.2^6)+(1.2^7)+(1.2^8)
=1.2+1.44+1.728+2.0736+(1.2^5)+(1.2^6)+(1.2^7)+(1.2^8)
=1.2+1.44+1.728+2.0736+2.488319999999999+(1.2^6)+(1.2^7)+(1.2^8)
=1.2+1.44+1.728+2.0736+2.488319999999999+2.985983999999999+(1.2^7)+(1.2^8)

=15.499085+4.299816959999998
=19.798902
答案:(1.2^1)+(1.2^2)+(1.2^3)+(1.2^4)+(1.2^5)+(1.2^6)+(1.2^7)+(1.2^8)=19.798902
