Question

(3×15la puterea 12 +2×15la puterea12 )
÷15la puterea 11+(3la 2+3la 2)÷(3la3+3la3)÷3+1la2005la0

Answer 1

5x15^(12-11)   +   2  x 3^2  : 2x3^3 : 3   +   1 -1 =
5x15  + 1 +1 - 1 = 75+1-1=76
----------------------------------------------------

Answer 2

(3x15¹²+2x15¹²):15¹¹+(3²+3²):(3³+3³):3+1¹⁰⁰⁵-2005⁰=76
=15¹²(3+2):15¹¹+2·3²:2·3³:3+1-1=
=15⁽¹²⁻¹¹⁾x5+1+1-1=
=15x5+1+1-1=
=75+1+1-1=
=76
