square root
2. you are wrong

a^2 can't solve as a/2
the opposite of square is square root
so the solve of a is
±√47

± means the answer can be + or -

我地小學六年級既textbook就有一課講平方同平方根
如果佢知平方根既反函數係平方既話佢就解到
但係對於冪係2既話
一定要係前面加“±”

呢D我4年班先識
我慢你一年 Evil or Very Mad

f.4既野走黎問我....

Lifesytle survey - 頁 2 Aoaa10

1. a(b+x+cy)^2=d^2
a(b+x+cy)=d
跟住唔識計..

你地講既4年班係f4定p4....

小學教過平方/平方根
同埋呢D係form 2既野 Very Happy

1. a(b+x+cy)^2=d^2
a(b+x+cy)=d
你忽略左個平方根...
應該係
a(b+x+cy)=d²
b=d²/a-x-cy

我地講緊P.4
唔洗驚...
我地有小小問題

~girl~ 2010-10-20, 23:32

唔係話square 既opposite=square root咩?
咁2邊都......
oh係喎我搞錯左 Laughing

點解你地p4就識

呢個係一條啱form 1仔/女答既問題：

如果a178b可以被12整除
（不是a×178×b
例：a=7 b=8既話
ab就等於78 ba就等於87）
求a178b的最小值

a<10

岩唔岩

當a 和 b等於一個特定的數時，
a178b便會被12整除，
求a178b的最小值
（不是a×178×b
例：a=7 b=8既話
ab就等於78 ba就等於87）
答案係一個五位數
（冇人叫你搶答）

唔知點解
淨係知個位數一定要係雙數
so 答案=11784/12=982

再將D數字加埋check邊個個萬位係1

可唔可以例條式出黎點計..

franco大竟然唔識
12既倍數係3同4既倍數
故可以被12整除到就要同時比3同4整除
a178b
從可以被4整除的法則可以推斷b一定係4/8
由於需要最小值
所以一開始試1
1+1+7+8+8=25 <--唔可以比3整除（比3整除係要所有位數既數字相加等於3的倍數）
估b=8 的可能性排除
所以答案就係11784
（11780係唔可以比3整除）

呢條係邏輯
所以冇式

其實係一條數學填充題
階乘的反函數是什麼？
