Answer 1

Answer:

a=4,b=20

Step-by-step explanation:

7+3√5/3+√5×3-√5/3-√5+7-3√5/3-√5×3+√5/3+√5=a+b√5b=a+b√5b

3(7+3√5)-√5(7+3√5)/(3)^2+(5)^2+3(7-3√5)+√5(7-3√5)/(3)^2-(√5)^2=a+b√5b

21+9√5-7√5-3√25/9-5+21-9√5+7√5-3√25/9-5

21+2√25-3×5/4+19√25-3×5/4

21+2×5-15/4 +19×5-3×5/4

21+10-15/4+95-15/4

31-15/4 +80/4

4+20

a=4,b=20

4+20√5b
