Answer 1

Hei! :)

(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

Answer 2

Răspuns:

1

Explicație pas cu pas:

((2^2)^2 : 2^2)^2 x (2^2)^18 : (2^8)^5 =

(2^4 : 2^2)^2 x 2^36 : 2^40 =

(2^2)^2 x 2^(-4) =

2^4 x 2^(-4) =

2^(4-4) =

2^0 =
