Question

9. By what least number should we divide the following to make it a perfect square?
(a) 1568
(b) 10224

Answer 1

Answer:

10224 ÷ 2 = 5112

5112÷2 = 2556

2556÷2 = 1278

1278÷2 = 639

639 ÷ 3 = 213

213 ÷ 3 = 71

Thus the prime factors are 2×2×2×2×3×3×71

Finding the least number to divide to form a perfect square is the same as finding the highest perfect square out of its factors.

Organize the factors into pairs of like prime factors

(2×2)×(2×2)×(3×3)×71

Everything paired is part of the highest perfect square factor, and what's left, 71, is the number you need to divide to get there. not sure check it follow me

Answer 2

Answer:

here is your answer

Step-by-step explanation:

first you have to take LCM of 1568 then the number that doesn't make pairs you have to write the language written in pic okay
