ПОМОГИТЕ С 179 И 180 ОТ А ДО Г !!

Answer 1

179
а)(5x-2y)²/[2y(5x-2y)]=(5x-2y)/2y
б)(2s-3t)(4s²+6st+9t²)/[3s(4s²+6st+9t²)]=(2s-3t)/3s
в)18b²(6a-b)/(6a-b)²=18b²/(6a-b)
г)9k(k+3l)/[(k+3l)(k²-3kl+9l²)]=9k/(k+3l)
180
а)(4a-b)²/[(4a-b)(16a²+4ab+b²)]=(4a-b)/(16a²+4ab+b²)
б)(2p+3q)(4p²-6pq+9q²)/(2p+3q)²=(4p²-6pq+9q²)/(2p+3q)
в)(5x-y)(25x²+5xy+y²)/(5x-y)²=(25x²+5xy+y²)/(5x-y)
г)(3n+4m)(9n²-12nm+16m²)/(3n+4m)²=(9n²-12nm+16m²)
