Answer:
a=0 ,b=1
Step-by-step explanation:
(7+3√5/3+√5)-(7-3√5/3-√5)
=(7+3√5)(3-√5)-(7-3√5)(3+√5)/(3+√5)
=(21-7√5+9√5-15)-(21+7√5-9√5-15)/3to the power 2,-(√5) to the power2
=(21-7√5+9√5-15-21-7√5+9√5+15)/9-5
=4√5/4
=√5
=(7+3√5/3+√5)-(7+3√5/3-√5)
=a+√5*b
=√5=a+√5*b
=0+√5*1=a+√5*b
=a=0,b=1
Can I now the second question too
