Question

please give ans. with solution ​

Answer 1

Answer:

Step-by-step explanation:

a-b= 4.....(1)

a+b=6......(2)

adding equations 1 and 2 , we get

a-b+a+b=6+4

2a=10

a=5

now, put the value of a in (2)

a+b=6

5+b=6

b=1

i)  a^{2} + b^{2}

=5^[2] + 1^[2]

= 25+1= 26

= 26  ANS..

ii)  ab

=5 * 1

=5 ANS..
