Verified answer

[tex]a) \frac{4}{11} + 2 = \frac{4}{11} + \frac{22}{11} = \frac{26}{11}[/tex]

[tex]b) \frac{-8^{x10} }{5^{X10} } + \frac{23}{50} = \frac{-80}{50} + \frac{23}{50} = \frac{-57}{50}[/tex]

[tex]c) \frac{1^{x3} }{5^{x3} } + \frac{2^{x5} }{3^{x5} } = \frac{3}{15} + \frac{-10}{15} = \frac{-7}{15}[/tex]

[tex]d) \frac{7^{x3} }{9^{X3} } - \frac{-1}{27} = \frac{21}{27} - \frac{-1}{27} = \frac{22}{27}[/tex]

Bonjour;

a) 4/11 + 2 =

4/11+ 2*11/11

= 4/11+22/11

=26/11

b) -8/5 + 23/50 =

-8/5*10/10 +23/50

= -80/50 +23/50

= -67/50

c) 1/5 + -2/3 =

1/5*3/3 -2/3*5/5

= 3/15 -10/15

= -7/15

d) 7/9  -1/27 =

7/9 *3/3 -1/27

= 21/27 -1/27

= 20/27

si c'est :

7/9 - (-1/27 )=

= 21/27 +1/27

= 22/27
