a. 1375
b. 625
c.1024
d.729
​

Answer 1

729 is the answer

Hope it’s help you

Answer 2

Answer:

1375

Step-by-step explanation:

1375 = 5×5×5×11

in this case, if we pair same numbers in groups of 2, the pairing wouldnt be equal..

hence , this is not a perfect square

625 = 5×5×5×5

this is a perfect square

1024 = 2×2×2×2×2×2×2×2×2×2

this is a perfect square as we can pair all numbers in groups of 2 , yet they will be equal

729 = 3×3×3×3×3×3

this is a perfect square

if u want, i have attached prime factorisation working.....

the pic is a bit shaky, but u can see

hope this us clear.....
