Am nevoie la a,b si c

Answer 1

a )

( - 2 ) · ( - 3 ) - ( - 7 ) - ( - 2 )⁴ = - 3

=  + 6 + 7 - 16 =

= 13 - 16 =

= - 3

______________

b)  2 / 3 - 2 / 3  ·   ( - 9 / 2 ) = 2 / 3 + 3 = 2 / 3 + 9 / 3 = 11 / 3 = 3 intregi si 2 / 3

__________________________________________

c)    2√3 + 3√3 - 7√3 = 5√3 - 7√3 = - 2√3

Answer 2

a )  ( -2)·( -3) - ( -7) - ( -2)⁴ =

= 6 + 7 - 16

= 13 - 16

= -3

b)  2/3 - 2/3·(-9/2) = 2/3 + 3 = 2/3 + 9/3 = 11/3

c)    2√3 + 3√3 - 7√3 = 5√3 - 7√3 = - 2√3
