Answer:
9486
Step-by-step explanation:
x= 99 and y= 5^3 = 125

Answer:
simplest form
Step-by-step explanation:
Simplest form is a method of converting the fraction to its lowest multiple.
For example, the fraction 25/100 isn't in its simplest form
Both the numerator and the denominator can be divided by 5. When divided by 5 the fraction becomes 5/20.
5/20 is still not in its simplest form because it can be divided by 5. When divided by 5, the fraction becomes 1/4.
1/4 is now in its simplest form because both the numerator and denominator cannot be divided by any other number
