Пояснення:
2 ) а ) . . . = ( 2⁶ : 2⁴ )/2² = 2² : 2² = 2⁰ = 1 ;
б ) . . . = ( 9 * 4 )⁻⁴/( 2 * 3 )⁻⁹ = 36⁻⁴/6⁻⁹ = ( 6² )⁻⁴/6⁻⁹ = 6⁻⁸/6⁻⁹ = 6¹ = 6 ;
в ) . . . = 5⁻⁴/5⁻⁵ * ( 6/3 )⁻³ = 5¹ * 2⁻³ = 5 * 1/8 = 5/8 .
3 ) а ) . . . = ( 2³ )⁻² * ( 2² )³ = 2⁻⁶ * 2⁶ = 2⁰ = 1 ;
б ) . . . = ( 3² )⁻⁶ * ( 3³ )⁵ = 3⁻¹² * 3¹⁵ = 3³ = 27 ;
в ) . . . = 1 : 10⁻³ = 10³ = 1000 ;
г ) . . . = ( 5³ )⁻⁴ : ( 5² )⁻⁵ = 5⁻¹² : 5⁻¹⁰ = 5⁻² = 1/5² = 1/25 ;
д ) . . . = 2⁻²¹/4⁻¹¹ = 2⁻²¹/( 2² )⁻¹¹ = 2⁻²¹/2⁻²² = 2⁻¹ = 1/2 ;
е ) . . . = [( 2² )⁻² * ( 2³ )⁻⁶ ]/2⁻²² = ( 2⁻⁴ * 2⁻¹⁸ )/2⁻²² = 2⁻²²/2⁻²² = 2⁰ = 1 ;
ж ) . . . = [ 3⁻¹⁰ *( 3² )⁸ ]/3⁻² = ( 3⁻¹⁰ * 3¹⁶ )/3⁻² = 3⁶/3⁻² = 3⁸ = 81² =6561 ;
з ) . . . = ( 5⁻⁵ *( 5² )¹⁰ )/( 5³ )³ = ( 5⁻⁵ * 5²⁰ )/5⁹ = 5¹⁵/5⁹ = 5⁶ = 15625 .
