加上以下數字,使算式成立

1,2,3,4,5,6,8 (不能重復)

4 x _ + 7 x _ = _ x 9 +_ x 10 + _^2 + _ ^2

✔ 最佳答案
4 X 6 + 7 X 8 = 4 X 9 + 1 X 10 + 5^2 + 3^2
以上都係等於80

4 x _ + 7 x _ = _ x 9 +_ x 10 + _^2 + _ ^2

答案:(4 X 6) + (7 X 8) = (4 X 9) +( 1 X 10) +( 5^2) +(3^2)

首先計算程序就系先乘除後加減

4x2 = 8
7x8 = 56 結果得出黎既數 = 8+56 = 64

1x9 = 9
5x10=50
4/2=2
6/2=3 結果得出黎既數 = 9+50+2+3 =64

答案如下:

4 x ( 2 ) + 7 x ( 8 ) = ( 1 ) x 9 + ( 5 ) x 10 + ( 4 ) ^2 + ( 6 ) ^2
