(1+0.25)^5等于多少,(1+0.25)^5等于多少,(1+0.25)^5等于多少,你是要估算?估算的话(1+0.25)^5=1+5x0.25+10X0.25^2+10x0.25^3=1+1.2

(1+0.25)^5等于多少,
(1+0.25)^5等于多少,

(1+0.25)^5等于多少,
你是要估算?
估算的话
(1+0.25)^5
=1+5x0.25+10X0.25^2+10x0.25^3
=1+1.25+2x1.25/4+10x0.25^3
=2.25+0.625+0.625/4
=2.875+0.15625
=3.03125
偏差在小数点后2位
直接算 就是
1+5/4+10/16+10/64+5/256+1/1024
=1+1.25+0.625+0.15625+0.01953125+0.0009765625
=3.051757813
或者 变成分数形式计算
(5/4)^5
=3125/1024 约等于3.1
=3.051757813

(1+0.25)^5
= 1.25^5
= 1.25 x 1.25 x 1.25 x 1.25 x 1.25
= 3.0517578125

(1+0.25)^5=(5/4)^5=3125/256=12.20703125
