1) (3X^2-1)(2X^2+1)=6X^4+X^2-1
2) (3X^2-1)(2X+1)=6X^3+3X^2-2X-1
16,3114 = t × 0,25
t = 16,3114 ÷ 0,25
t = 163114 ÷ 2500
t = 65,2456
Ответ: 65,2456
(√a³ -a)/(a -2a^1/2 +1) =(a√a -a)/( (√a)² -2√a +1) =a(√a-1)/(√a -1)² =a/(√a-1) .
-------------------
не знаю
( 1/a^(√2 -1) ) ^(√2 +1) * a ^(√2+1) = 1/(a^(√2 -1)(√2+1)*a^(√2+1)=
1/(a^(2 -1) *a^(√2+1) = (1/a)*(a^√2) *a = a^√2.
