Упростите выражение
(5a³-4b²)²+(4b²+5a³)²

Answer 1

25a^6-40a^3b^2+16b^4+16b^4+40b^2a^3+25a^6=50a^6+32b^4

Answer 2

$(5a {}^{3} - 4b {}^{2} ) {}^{2} + (4b {}^{2} + 5a {}^{3} ) {}^{2} \\ 25a {}^{6} - 40a {}^{3} b {}^{2} + 16b {}^{4} + 16b {}^{4} + 40a {}^{3} b {}^{2} + 25a {}^{6} \\ 50a {}^{6} + 32b {}^{4}$
