Question

The value of 4 and 5 if a&b=ab²

Answer 1

Step-by-step explanation:

=ab(a+b)

Given,

a=1/(3–2√2)

b=1/(3+2√2)

Now,

ab= 1/(3–2√2)×1/(3+2√2) = 1/{(3)²-(2√2)²}

= 1/(9–8) = 1

a+b = 1/(3–2√2)+1/(3+2√2)

= (3+2√2+3–2√2)/{(3)²-(2√2)²} = 6/(9–8) = 6/1

= 6

Therefore, a²b+ab² = ab(a+b) = 1/6 [Ans].
