b=sqrt(17^2-8^2)+sqrt(3)sqrt(38^2)-37^2

解答

b = 1 7^{2} - 8^{2} + 3 3 8^{2} - 3 7^{2}

b = 383 - 1354

十进制

b = - 1288.18206 \dots

求解步骤

b = 1 7^{2} - 8^{2} + 3 3 8^{2} - 3 7^{2}

化简

1 7^{2} - 8^{2} + 3 3 8^{2} - 3 7^{2} : 383 - 1354

b = 383 - 1354

so l v e f or x, 95 x + 90 y = 50

4 = 10 x^{- 0} 0.15

so l v e f or x, 2 x + y = 84

x + 3 - x + 2 = 5

so l v e f or x, (x + p) (y + q) = 3
