3^24 = (3^12)^2

13^78 = (13^39)^2

19^25 × 19^7 = 19^32 = (19^16)^2

2^72 = (2^36)^2

25^37 = (5^37)^2

4^75 = (2^75)^2

625^9 = (5^4)^9 = 5^36 = (5^18)^2

9^27 = (3^27)^2

121^121 = (11^121)^2

(2×8)^17 = (2^4)^17 = 2^68 = (2^34)^2

32^19 : 2^19 = (32:2)^19 = 16^19 = (4^19)^2

81^125 = (9^125)^2 = (3^250)^2
