The square root of 2. Three roots (hint: multiply the first two times mentioned above, and then find the roots up and down to get the root number score of the whole, and the score can be directly transformers 3 ",the square root of 3).

14 +4 times square 3 (note: square difference formula [(AB)] * (A+B) = A square -B square), followed by a complete square formula [(A+B) square = A square +B square -2AB] [AB].

Constant formula generation, you can find the answer)

4.6 (hint: any number is equal to 1) The square root of the second time, 0 12, root number 3,No. 12, becomes 3 to 4 times that of the second time, and the square root of 2 multiplied by the sum of square root 3 and root is 3.4 times that of the last time.

Multiply by the square root of 5, and then 3 = the five roots below, and then use the sum behind. )

59,365,438+09 comes from the product of 65,438+03,3,3.

3×3×3× 13× 13× 13 = 593 19

So a 3 and a 13 are paired and got.

3× 13×3× 13×3× 13 = 593 19/>39×39×39 = 59 3 19

② First of all, it is a multiple of 3, it is a multiple of 27, and 59 3 19/27 = 2 197.

2 197, not a multiple of 3, was only 3 cubic meters at the end of July, so it might be 13, and it was 13 cubic meters, so it was 39 cubic meters.

Quadrilateral ABCD diamond

AD = CD AD parallel BC DC parallel AE

The other angle DAB = 60

Angle CBE = 60

So the angle DCB = 60

Angle DBA = 60 Angle DBA = 60 (one angle of the diagonal of a parallel diamond = 60 bisects the other angle 120 equals 60).

So the angle ACB = 30° (the diagonal of the diamond is parallel to the diagonal, because the angle = 6? 0, so the other angle is 30)

CE vertical communication

Triangle CDB and triangle CEB

Because of the angle, the angle BCE = 60

BCD = Angle BCE = 60 Angle CBE = Angle CBD = 60 CB = CB.
