(а^36-а^3)/(а^26+а^(15 )+а^4 ) сократите дробь плиииз

Answer 1

$frac{a ^{36}-a ^{3} }{a ^{26}+a ^{15}+a ^{4} }}= frac{a ^{3} (a ^{33}-1) }{a ^{4} (a ^{22}+a ^{11} +1) } = frac{(a ^{11}) ^{3}- 1 ^{3} }{a(a ^{22}+a ^{11}+1) } = frac{(a ^{11}-1)(a ^{22} +a ^{11} +1) }{a(a ^{22}+a ^{11} +1) } = frac{a ^{11}-1 }{a}$
