Answer:
2^2 ( 1,2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44,48
3^2(1,2,3, 5) = 9, 18, 27, 45
5^2(1, 2) = 25, 50
7^2 = 49

2³·3²·x·y²
Unique prime factors are 2, 3, x, y. Each of those is raised to a power to obtain the given expression.
72xy² = 8·9·x·y² = 2³·3²·x·y²
n = 60
<em>Terms which are divisible by 9 between 60 and 600. </em>
<em> 63, 72, 81, ........ 594 </em>
<em> n = [ (l - a)/d ] + 1 </em>
<em> n = [(594 - 63)/9] + 1 </em>
<em> n = (531/9) + 1 </em>
<em> n = 59 + 1 </em>
<em> n = 60</em>
