Answer 2

Answer:

According to question,

√(13 - a√10) = √8 + √5

Squaring on both sides

={√(13 - a√10)}²= (√8 + √5)²

=13 - a√10= (√8)² + 2x√8x√5 + (√5)²

=13 - a√10= 8 + 2√40 + 5

=13 - a√10= 13 + 2x2√10

=13 - a√10= 13 + 4√10

=13 - 13 - a√10= 4√10

= -a√10= 4√10

= -a= 4√10/√10

= -a= 4

= a= -4

Therefore,

a= -4
