(√ 2-1) ∧ 2 + √ 8 calculation (∧ 2 is the square)

(√ 2-1) ∧ 2 + √ 8 calculation (∧ 2 is the square)

(√2 -1)^2
=2 -2√2 +1=3- 2√2,
And √ 8 = 2 √ 2,
therefore
(√2 -1)^2 +√8
=3- 2√2 +2√2
=3

(- 3 / 4AB) square × (- 9 / 2 a square b-12ab + 3 / 4B Square)
(- 4 / 3 AB) squared × (- 9 / 2 a squared b-12ab + 4 / 3 B squared)),

(- 3 / 4AB) square × (- 9 / 2 a square b-12ab + 3 / 4B Square)
=(16 / 9A & # 178; B & # 178;) × (- 9 / 2 a squared b-12ab + 3 / 4 B squared)
=-The fourth power of 8A B & # 179; - 64 / 3A & # 179; B & # 179; + 64 / 27a & # 178; b
If you don't understand this question, you can ask,

a. B satisfies a (a |) - A (square of a + 2b) = I, find the value of square of a + 4AB + 4B + 2A + 4B

A (a |) 1 (square of a + 2b) = I
The square of a + the square of a-a-2b = 1 deduces the square of a-2b = 1 a-4ab + the square of 4b-2a + 4B = (a-2b) - 2 (a-2b) = 1-2 = - 1
