with steep by steep ​

Answer 1

Answer:

1) 7

2) 5

Step-by-step explanation:

1) 2800 = 2⁴ × 5² × 7.

Therefore factor with odd power is 7.

If we divide by 7 then it will be 400 which is (2²×5)² ie. 20².

2) 1620 = 2²×3⁴×5

Factor with odd power = 5.

If we divide by 5 then it will be 324 which is (2×3²)² ie. 18².

Hope this helps !
