Question

Tìm x :

x * x * x * x * x * 9999 = 319968

Answer 1

x^5 * 9999=319968

x^5=319968: 9999

x^5=32

x=2

Answer 2

x * x * x * x* x * 9999 = 319968

<=> 5x * 9999 = 319968

<=> 5x = 319968 : 9999

<=> 5x = 32

<=> x = 32 : 5

=> x = 6,4

Vậy x = 6,4

Answer 3

X*X*X*X*X=319968:9999

X*X*X*X*X=32

X=2 vì 2*2*2*2*2=32

Answer 4

Xin lỗi mình làm nhầm :

<=> x^5 * 9999 = 319968

<=> x^5 = 319968 : 9999

<=> x^ 5 = 32

=> x = 2

Vậy x = 2
