Explicație pas cu pas:

16*25 = 4^2*5^2 = (4*5)^2 = 20^2 patrat perfect

2^18*3^6 = (2^9)^2*(3^3)^2 = (2^9*2^3)^2 patrat perfect

25*3^18 = 5^2*(3^9)^2 = (5*3^9)^2 patrat perfect

16*100 = 4^2*10^2 = (4*10)^2 = 40^2 patrat perfect

4^15*121^17 = (2^2)^15*(11^2)^17 = (2^15)^2*(11^17)^2 = (2^15*11^17)^2 patrat perfect

5^14*7^8*13^24 = (5^7)^2*(7^4)^2*(13^12)^2 = (5^7*7^4*13^12)^2 patrat perfect

3^25 + 3^34 = 3^25(1 + 3^9) = 19684*3^25 = 59049*3^24 = 243^2*3^24 =

= (243*3^12)^2

2^25 - 7*2^20 = 2^20(2^5 - 7) = 2^20*(32 - 7) = 2^20*25 = (2^10*5)^2 patrat perfect
