Se dau nr.x=27^3÷9^3+3-(3^3×2^5)^6÷(3^17×2^30) si y=3×(5+2×3-2430÷405) sa se calculeze x^y÷(3^4)^11. Multumesc

Răspuns :

x=27^3÷9^3+3-(3^3×2^5)^6÷(3^17×2^30)

x=3^9:3^6+3-(3^18 · 2^30):(3^17×2^30)

x=3^3+3-3

x=3^3

y=3×(5+2×3-2430÷405)

y=3·(5+6-6)

y=15

x^y÷(3^4)^11=

=(3^3)^15 : 3^(4·11)

=3^(45-44)

=3
