MULTIPLICATION AND DIVISION
〖 7a〗^3 2a^5 = 〖 7a〗^3 . 2a^5 = 〖 7a〗^3 x 2a^5 = (7x2) x (〖 a〗^3 x a^5)
= 14 x a^(3+5) = 14 x a^8 = 14a^8
Find each product (cari hasilnya) and represent it in the simplest form!(nyatakan dalam bentuk yang paling sederhana)
Example:
8a^4 . 3a
= 8a^4 x 3a (is equal to eight a to the fourth times three a)
= ( 8 x 3 ) x (a^4 x a ) (is equal to eight times three times a to the fourth times a
= 24 x (a^4 x a^1) (is equal to twenty four times a to the fourth times a to the first)
= 24 x a^(4+1) (is equal to twenty four times a to the fourth plus one)
= 24a^5 (is equal to twenty four a to the fifth)
