最佳解答:

√0.25=√(25/100)=(√25) /(√100)=5/10=0.5 √1.69=√(169/100)=(√169) /(√100)=13/10=1.3 √0.0064=√(64//10000)=(√64) /(√10000)=8/100=0.08 - √1.44=- √(144/100)=- [(√144) /(√100)]=- [12/10]=-1.2 - √0.0064=- √(64//10000)=- [(√64) /(√10000)]=- [8/100]=-0.08 - √2.25=- √(225/100)=- [(√225) /(√100)]=- [15/10]=-1.5 2009-01-01 16:46:31 補充: trachelium_7呢位仁兄,其實可以唔使抄到足!

其他解答:

√0.25] = √(25/100) = (√25) /(√100) = 5/10 = 0.5 _______________________________________________________ √1.69 = √(169/100) = (√169) /(√100) = 13/10 = 1.3 _______________________________________________________ √0.0064 = √(64//10000) = (√64) /(√10000) = 8/100 = 0.08 _______________________________________________________ - √1.44 = - √(144/100) = - (√144) /(√100) = - 12/10 = -1.2 _______________________________________________________ - √0.0064 = - √(64//10000) = - (√64) /(√10000) = - 8/100 = -0.08 _______________________________________________________ - √2.25 = - √(225/100) = - (√225) /(√100) = - 15/10 = -1.5 _______________________________________________________ besides this kinds method 你可以記低依啲 唔使計鬼死甘耐先得. 2^2 = 4 3^2 = 9 4^2 = 16 5^2 = 25 6^2 = 36 7^2 = 49 8^2 = 64 9^2 = 81 10^2 = 100 11^2 = 121 12^2 = 144 13^2 = 169
