Then need not necessarily be an integer. For example, 2 and 3 are integers but
is not an integer. So the first option , namely, integers are closed under division is not true.

Answer:
x = 2
Step-by-step explanation:
Note that 25 = 5² , then
= 5²
Since the bases on both sides are 5 then equate the exponents
6 - 2x = 2 ( subtract 6 from both sides )
- 2x = - 4 ( divide both sides by - 2 )
x = 2
