Question

Rezultatul calcului (3^2+3×3^4×3^9):(9+3^7:3^2+27^3)este egal cu.

Answer 1

(3²+3x3⁴x3⁹) :(9+3⁷:3²+27³) = (9+3¹⁺⁴⁺⁹):[9+3⁷⁻²+(3³)³] =

= (9+3¹⁴):(9+3⁵+3⁹) = 3²(1+3¹²) :[3²(1+3³+3⁷) = (3¹²+1):(3⁷+3³+1)

Enuntul corect era urmatorul :

(3²+3x3⁴x3⁹) :(9+3⁷:3²x27³) = (9+3¹⁺⁴⁺⁹):[9+3⁷⁻²x(3³)³] =

= (9+3¹⁴):(9+3⁵x3⁹) = (9+3¹⁴):(9+3⁵⁺⁹) = (9+3¹⁴):(9+3¹⁴) = 1

Answer 2

(3^2+3×3^4×3^9):(9+3^7:3^2x27^3) = (3^2 + 3^14) : (3^2 + 3^5x3^9) =

=(3^2 + 3^14) : (3^2 + 3^14) =1
