bonjour

3 ⁷ x 4 ⁸ x 5 ⁴  :  2 ⁵ x 5 ⁻⁷ x 9 ³

= 3 ⁷ x ( 2² ) ⁸ x 5 ⁴ : 2 ⁵ x 5 ⁻⁷ x ( 3²) ³

=  3 ⁷ x 2 ¹⁶ x 5 ⁴ :  2 ⁵ x 5 ⁻⁷ x 3 ⁶

=  2 ¹¹ x 3  x 5 ¹¹

AYUDA

bsr

(3⁷ x 4⁸ x 5⁴) / (2⁵ x 5⁻⁷ x 9³)

= (3⁷ x 2⁸ x 2⁸ x 5⁴) / (2⁵ x 5⁻⁷ x 3³ x 3³)

= (3⁷ x 2¹⁶ x 5⁴) / (2⁵ x 5⁻⁷ x 3⁶)

= 3⁷⁻⁶ x 2¹⁶⁻⁵ x 5⁴⁺⁷

je vous laisse terminer
