a) a-b+(c-d)
b) a square + b square
​

Answer 1

Answer:

a ) 1/4

b ) (-1/4)

c ) 3

d)  (-2)

Step-by-step explanation:

A)  a-b+(c-d)

    a-b+(c-d)

=  1/4 - (-1/4) + ( 3 - (-2) )

=  1/4 + 1/4 + ( 3 + 2 )

=  ( 1+1 )/4 + 5

=  (2/4) + 5

=  1/2 + 5

=  1/2 + ( 5/1 * 2/2)

=  (1 + 10)/2

=  11/2

B)   a^2 + b^2

     a^2 + b^2

=  1/4^2 + (-1/4)^2

=  1/4^2 - 1/4^2

=  (1/4*1/4) - (1/4*1/4)

=  (1/16 - 1/16

=  (1 - 1)/16

= 0/16

=  0
