Explicație pas cu pas:

(4²:2²)²·4¹⁸:256⁵ = ?

(4²:2²)²·4¹⁸:256⁵ = [(2²)²:2²]²·(2²)¹⁸:(2⁸)⁵ = [2²ˣ²:2²]²·2²ˣ¹⁸:2⁸ˣ⁵ =

= (2⁴:2²)²·2³⁶:2⁴⁰ = (2⁴⁻²)²·2³⁶:2⁴⁰ = 2²ˣ²·2³⁶:2⁴⁰=

=2⁴⁺³⁶⁻⁴⁰ = 2⁰ = 1

(42:14)²x 9¹⁸:27⁶ = 3² x (3²)¹⁸ : (3³)⁶ = 3²x3³⁶:3¹⁸ = 3²⁺³⁶⁻¹⁸=

=3²⁰

(4 ^2 :2 ^2) ^2 ×4 ^18 :256 ^5 =

(4 ^2 :4) ^2 ×4 ^18 :(4 ^4) ^5=

(4 ^(2-1))^2 ×4 ^18 :4 ^(4×5)=

(4^1)^2 ×4 ^18 :4^20 =

4 ^2 ×4 ^18 :4^20 =

4 ^(2 +18):4^20=

4 ^20 :4 ^20 =
