Answer 1

Răspuns

Explicație pas cu pas:

(5x)*(3x) = 15x^2

_________

(-9xy)*(-5abx) = 45abx^2y

_________

(-7/3 xyz^2)*(3/4x^2z^-2) = -7/4x^3y

__________

(0,4uvw^2)*(-6xuv^2w^-3) = -12/5xu^2v^2w^-1

_________

(12xyc)*(-0,(3)xya) = -4x^2y^2ca

0,(3) = 3/9

___________

(1/5ab)*(1/4ac)*(1/8cd)*(-5xyc) = -1/32a^2bc^3dxy

____________

[(-1)^2n-1x^2y]*[(-1)^2nxy^2] = (-1)^4n-1x^3y^3

____________

(xyz)^m+n+p

2

a) -125x^3y^3

b) -5x^3y^3

c) 2x^4y^6

d)2,56x^2y^4

e) nu se vede clar

f) 0,(3) = 3/9

0,(4) = 4/9

3/9*4/9 = 12/81 = 4/27

4/27a^2b^5c^3

g) 6√15x^8y^18a^10b^3
