Question

(2,3c-9,1z^3-4)-(10z^3-3c+5,9)
и
(0,8t^2-20m+5)-(41-3m-2,4t^2)
ответ пожалуйста с решением ​

Answer 1

№ 1

$(2.3c - 9.1z {}^{3} - 4) - (10z {}^{3} - 3c + 5.9) = 2.3c - 9.1z {}^{3} - 4 - 10z {}^{3} + 3c - 5.9 = 5.3c - 19.1z {}^{3} - 9.9$

№2

$(0.8t {}^{2} - 20m + 5) - (41 - 3m - 2.4t {}^{2} ) = 0.8t {}^{2} - 20m + 5 - 41 + 3m + 2.4t {}^{2} = 3.2t {}^{2} - 17m - 36$
