Tolong di jawab bersama langkah langkah nya kak terimakasih
Jawab:
6. 3a^2 x 4a^3 = (3 x 4) x (a^2 x a^3)
= 12 x a^(2+3)
= 12a^5
7. 4ab^3 x 2a^3 b^4 = (4 x 2) x (a^1 x a^3) x (b^3 x b^4)
= 8a^(1+3)b^(3+4)
= 8a^4 b^7
8. 12 a^4 b^7 : 6a^2 b^5 = (12:6) x (a^4:a^2) x (b^7:b^5)
= 2 x a^(4-2) x b^(7-5)
= 2a^2 b^2
9. 20y^8 : 5y^5 = (20 : 5) x (y^8 : y^5)
= 4 x y^(8-5)
= 4y^3
10. 2a b^2 c^3 x 5a^3 bc^2 = (2 x 5) x (a^1 x a^3) x (b^2 x b^1) x (c^3 x c^2)
= 10 x a^(1+3) x b^(2+1) x c^(3+2)
= 10a^4 b^3 c^5
