4)52+72:х=56 помогите решить плз

X^8*X^4=X^(8+4)= X^12

<span>
1) 24/60 = 2/5   (сокращаем на 12)</span>

<span />24 = 2*2*2*3              60=2*2*5*3              НОД(24;60) = 12

2)  45 =5*3*3        105= 5*3*7                 НОД(45;105) = 15

45/105 = 3/7

3)   39 = 3*13                    130 = 2*5*13                НОД(39;130) = 13

39/130 = 3/10

4)  64 = 2*2*2*2*2             144 = 2*2*2*2*3*3       НОД(64;144) = 16

64/144 = 4/9
