Answer:8
Step-by-step explanation:
Given that
(
�
−
5
)
2
(
�
−
6
)
2
=
0
(a−5)
2
(b−6)
2
=0, this implies that either
(
�
−
5
)
2
=
0
(a−5)
2
=0 or
(
�
−
6
)
2
=
0
(b−6)
2
=0, or both are zero.
When
(
�
−
5
)
2
=
0
(a−5)
2
=0,
�
=
5
a=5, and when
(
�
−
6
)
2
=
0
(b−6)
2
=0,
�
=
6
b=6.
So, the sum
�
+
�
−
3
a+b−3 would be:
5
+
6
−
3
=
8
5+6−3=8
Therefore, the value of
�
+
�
−
3
a+b−3 is
8
8.
