Răspuns:

Explicație pas cu pas:

b)

√81*625 = √3^4*5^4 = √(3^2*5^2)^2 = 3^2*5^2 = 225

c)

√5^4*17^10 = √(5^2*17^5)^2 = 5^2*17^5 = 25*11419857 = 35496425

d)

√2020^2*2^2020 = √(2020*2^1010)^2 = 2020*2^1010

e)

√22^2*3^4*2^6 = √(22*3^2*2^3)^2 =22*3^2*2^3 = 1584

f)

√5^6*7^4*10^8 = √(5^3*7^2*10^4)^2 = 5^3*7^2*10^4 = 61250000
