mình ko biết đâu nhé bạn

@ĐẠI BẠCH , Uk bn ko bít thì thoi 

Có dòng chữ màu đỏ thì e chịu nhưng dấu k chọn màu xanh lá cây là giáo viên trong OLM k nha.

HOK TỐT

Ok bạn

1, Tìm x thuộc Z:

a) x²=100

=> x^2 = 10^2

=> x = 10

Vậy x = 10

b) ( x-5)²-7=9

 =>  ( x - 5 )^2 = 9 + 7 

=>   ( x - 5 )^2 = 16

=>   ( x - 5 )^2 = 4 ^ 2

=>    x - 5 = 4 

=> x = 5 + 4 

=> x = 9

kick nhé

a) \(x^2=100\)

\(=>x^2=10^2\)

\(=>x=10\)

b) \(\left(x-5\right)^2-7=9\)

\(=>\left(x-5\right)^2=9+7\)

\(=>\left(x-5\right)^2=16\)

\(=>\left(x-5\right)^2=4^2\)

\(=>x-5=4\)

\(=>x=4+5\)

\(=>x=9\)

2 bn lm thiếu rồi

a) x²=100

=> x = 10 hoặc -10

vậy............

b) ( x-5)²-7=9

=> ( x-5)² = 9 + 7

=> ( x-5)² = 16

+) ( x-5)² = 4²

=> x-5 = 4

=> x = 4+5

=>x=9

+) ( x-5)² = (-4)²

=> x-5 = -4

=> x = -4 + 5

=> x = 1

vậy x = 1 hoặc 9

chả hiểu gì

Ê ko hiểu thì bớt cái mỏ sân si lại nhá
