Answer 1

Answer:

35

Step-by-step explanation:

a=√2+1

√2-1

a=√2+1×√2+1

√2-1×√2+1

a=(√2+1)²

b=√2-1

√2+1

b=√2-1×√2-1

√2+1×√2-1

b=(√2-1)²

a²+ab+b² can be written as

(a²+b²+2ab)-ab

(a+b)²-ab

((√2+1)²+(√2-1)²)²-{(√2+1)²(√2-1)²}

(2+1+2√2+2+1-2√2)²-{(2+1+2√2)(2+1-2√2)}

(3+2√2+3-2√2)²-{(3+2√2)(3-2√2)}

(6)²-{9-6√2+6√2-8}
