Calculati:
7^2:{17^2:289+2[(2^3×3)^15:(2×2^43×3^15)+1^50]}

Pas cu pas va rog si sa explicati

Answer 1

7²: {17²:17²+ 2[( 2³x3)¹⁵: ( 2x2⁴³x3¹⁵) +1⁵⁰]}=
=7² : [ 17⁽²⁻²⁾ + 2(2³ˣ¹⁵x3¹⁵ : 2¹⁺⁴³x3¹⁵+1)]=
=7² : [17⁰+2(2⁴⁵x3¹⁵ : 2⁴⁴x3¹⁵+1)]=
=7²:[ 1 +2 (2⁽⁴⁵⁻⁴⁴⁾x3⁽¹⁵⁻¹⁵⁾ +1)]=
=7²: [ 1+2 ( 2¹x3⁰+1)]=
=7² : [ 1+2 (2x1+1)]=
=7² : ( 1+2×3)=
= 7² : 7=
=7⁽²⁻¹⁾=
=7
