b) ( 7¹⁴ x 5 )² : 7²⁶ = 7 ⁽ ¹⁴ ˣ ² ⁾ x 5² : 7²⁶ = 7²⁸ x 5² : 7²⁶ =
= 7² x 5² = ( 7 x 5 )² = 35²= 1 225

e) ( 11²⁰¹¹ x 4¹⁰⁰⁵ ) : [ ( 22² ) ⁵ ] ²⁰¹ = 11
= ( 11 ²⁰¹¹ x 2² ˣ ¹⁰⁰⁵ ) : 22 ² ˣ ⁵ˣ²⁰¹ =
= ( 11²⁰¹¹ x 2²⁰¹⁰ ) : 22²⁰¹⁰ =
= 11 x 22²⁰¹⁰ : 22 ²⁰¹⁰ =
= 11

f) 2²³ : 2²¹ : 2 + 3³² : 3³¹ x 3 = 11
= 2 ⁽ ²³ ⁻ ²¹ ⁻ ¹ ⁾ + 3 ⁽ ³² ⁻ ³¹ ⁺ ¹ ⁾ =
= 2¹ + 3² =
= 2 + 9 =
= 11
