Answer 2

$<b>Heya mate. (^_-). Solution below.$
====================================

• Firstly, finding the square root of 15625 by prime factorization method -


5 | 15625
________

5 | 3125
________

5 | 625
________

5 | 125
________

5 | 25
________

5 | 25
________

5 | 5
________

| 1



• So, √15625 = √(5 × 5 × 5 × 5 × 5 × 5)

=> √15625 = (5 × 5 × 5)

=> √15625 = 125




• Now, √ 15625 = 125



• So, √156.25

= √15625/100

= √(125 × 125)/(10 × 10)

= 125/10

= 12.5



• And, √1.5625

= √15625/10000

= √(125 × 125)/(100 × 100)

= 125/100

= 1.25




• Now,

√156.25 + √1.5625

= 12.5 + 1.25

= 13.75
