Question

9. Calculează:a)√ 5⁴/7² b) √1/3^8 c) √10^6/2^10 d) √7²/3^6 e) √8⁴/5^6 f) √2¹²/3^10​

Answer 1

Răspuns:

Explicație pas cu pas:

a)√ 5⁴/7² = 5^2 / 7 = 25/7 = 3 4/7

b) √1/3^8 = 1/3^4 = 1/81

c) √10^6/2^10 = 10^3 / 2^10 = 2^3 x 5^3 / 2^10 = 5^3 / 2^7 = 125/ 128

d) √7²/3^6 = 7/3^3 = 7/27

e) √8⁴/5^6 = 8^2 / 5^3 = 64/125

f) √2¹²/3^10​ = 2^6 / 3^5 = 64/ 729
