A^m*a^n = a^(m+n)
a^m / a^n = a^^(m-n)
a^m*b^m = (ab)^m
(a^m)^n = a^(mn)
3^17*6^16 / 18^15 = 3*3^16*6^16 / 18^15 = 3 * 18^16 / 18^15 = 3* 18^(16-15) = 3*18 = 54
Номер 67 ответ - Е (28)
(x+32)/(x+8)=3
(x+32)=3(x+8)=3x+24
32-24=3x-x
8=2x
x=4
4+24=28
<em>y=(x³+x²)/(x+1)+2=x²(x+1)/(x+1)+2=x²+2, x≠-1.</em>
-1 7\9=-16\9
(-16\9)^2=256\81
