tanda tambahnya di ganti sama bagi

A.) 20a^7 : 5a⁴ = 4a³.
B.) 15a^6b^5 : 3a⁴4b⁴ = 5a²b.
C.) 7x²y³ : 7xy = xy².
D.) 9a⁴b^7 : 3a⁴b⁴ = 3ab³.

NB : ^ (dibaca pangkat).



Maaf jika salah. Semoga membantu ^_^

a. 20a^7 : 5a^4
=(20 : 5) × (a^7 : a^4)
=4×a^3
=4a^3
.
b.15a^6 b^5 : 3a^4 b^4
=(15 : 3) × (a^6 :a^4) × (b^5 : b^4)
=5 × a^2 × b
=5a^2b
.
c.7x^2 y^3 : 7xy
=( 7 : 7) × (x^2 : x) × ( y^3 : y )
=1 × x × y^2
=xy^2
.
d.9a^4 b^7 : 3a^4 b^4
= (9 : 3) × ( a^4 : a^4 ) × ( b^7 : b^4 )
= 3 × 1 × b^3
=3b^3
.
