Answer 1

Answer:

1) multiply by 5

2) divided by 5

Step-by-step explanation:

1) 180

180= 2×2×3×3×5

to get perfect square we need pair of 5

therefore multiply 180 with 5

180×5 = 900

900 is square of 30

2) 3645

3645 = 3×3×3×3×3×3×5

to get a perfect square divide 3745 by 5

3645 ÷ 5 = 729

729 is square of 27
