6) Apti Square Roots and Cube Roots等于

  1. 1
  2. 2
  3. 2 +Apti Square Roots and Cube Roots
  4. 2Apti Square Roots and Cube Roots

答案: B

说明

设 x =Apti Square Roots and Cube Roots

x =Apti Square Roots and Cube Roots

= x2 = 2 + x

= x2 - 2 - x = 0

= x2 -(2-1) x - 2 = 0

= x2 - 2x + x - 2 = 0

= x (x - 2) + 1 (x - 2) = 0

= (x - 2)(x + 1) = 0

= x = 2, x = -1

解决方案 2

Apti Square Roots and Cube Roots

在相同类型根值相加的情况下,将给定的数字分解为连续的顺序,最大的数字将是答案,即数字为 2,两个连续顺序为:1*2 因此,答案是 2


7) Apti Square Roots and Cube Roots的值是

  1. 30.297
  2. 30.197
  3. 30.097
  4. 30.397

答案: A

说明

Apti Square Roots and Cube Roots

Apti Square Roots and Cube Roots

=30 + 0.3 - 0.003 = 30.297


8) 如果 Apti Square Roots and Cube Roots= 12.3,则 x 的值是

Apti Square Roots and Cube Roots

答案: D

说明

Apti Square Roots and Cube Roots

5 + x2 = 9

x2 = 9 - 5 = 4

x = 2
