me ajuda ae pffffffffffffff

Answer 1

Resposta:

)   a) 4a^4b^4c^44a4b4c4

     b) 30x^3y^4z30x3y4z

Explicação passo-a-passo:

a)

\frac{20a^6b^3c^9}{5a^2b^{-1}c^5} = 4a^{6-2}b^{3-(-1)}c^{9-5} = 4a^4b^{3+1}c^4 = 4a^4b^4c^45a2b−1c520a6b3c9=4a6−2b3−(−1)c9−5=4a4b3+1c4=4a4b4c4

b)

5xyz \times 6x^2y^3 = 30x^{1+2}y^{1+3}z = 30x^3y^4z5xyz×6x2y3=30x1+2y1+3z=30x3y4z
