vă dau coroane va rog frumos​

Answer 1

Explicație pas cu pas:

(7•8)³ = 7³•8³ = 7³•(2³)³ = 7³•2⁹

(5•11•7)⁵ = 5⁵•11⁵•7⁵

12⁶ = (2²•3)⁶ = (2²)⁶•3⁶ = 2¹²•3⁶

(13⁷•9)³ = (13⁷•3²)³ = (13⁷)³•(3²)³ = 13²¹•3⁶

(7⁸•12⁴)² = [7⁸•(2²•3)⁴]² = [7⁸•(2²)⁴•3⁴]² = (7⁸•2⁸•3⁴)² = (7⁸)²•(2⁸)²•(3⁴)² = 7¹⁶•2¹⁶•3⁸

[(3⁷)⁵•2⁵]⁴ = (3³⁵•2⁵)⁴ = (3³⁵)⁴•(2⁵)⁴ = 3¹⁴⁰•2²⁰

= [a•(b⁶⁴)²•c⁸]² = (a•b¹²⁸•c⁸)² = a²•(b¹²⁸)²•(c⁸)² = a²•b²⁵⁶•c¹⁶

${( {a}^{n} \cdot {b}^{m})}^{p} = {( {a}^{n})}^{p} \cdot {({b}^{m})}^{p} = {a}^{np} \cdot {b}^{mp}$
