Explanation:

name the missing term as x.

--> 7^16 / 7^12 = 7^ -18 / x

cross multiply to find the value of x.

7^16 × X = 7^12 × 7^ -18

now use this property :

a^x × a^y = a^x+y

7^16 × X = 7^12 + -18

7^16 × X = 7^-6

divide both sides by 7^16 to solve for X.

X = 7^-6/ 7^16

Property for division :

a^x÷a^y = a^x-y

X = 7^-6-16

X = 7^-22
