Замените символ * таким одночленом, чтобы выполнялось равенство:
а) $* ⋅ 3b^2 = 9b^3$;
б) $8a^2b^4 ⋅ * = -8a^5b^5$;
в) $-4a^3b^4 ⋅ * = 16a^7b^9$;
г) $-17a^8b^{12} ⋅ * = -34a^9b^{13}$.
$* ⋅ 3b^2 = 9b^3$
$* = 9b^3 : 3b^2$
$* = 3b$
$3b ⋅ 3b^2 = 9b^3$
$8a^2b^4 ⋅ * = -8a^5b^5$
$* = -8a^5b^5 : 8a^2b^4$
$* = -a^3b$
$8a^2b^4 ⋅ (-a^3b) = -8a^5b^5$
$-4a^3b^4 ⋅ * = 16a^7b^9$
$* = 16a^7b^9 : (-4a^3b^4)$
$* = -4a^4b^5$
$-4a^3b^4 ⋅ (-4a^4b^5) = 16a^7b^9$
$-17a^8b^{12} ⋅ * = -34a^9b^{13}$
$* = -34a^9b^{13} : (-17a^8b^{12})$
$* = 2ab$
$-17a^8b^{12} ⋅ 2ab = -34a^9b^{13}$
