= 3× (2 )× [4× (2 roots 2) ÷ (4 )× 6× 4 × (2 roots)
=3×2×2 root number 2×6×4 root number 2
=6×6×8× (root number 2) 2
=36×8×2
=36* 16
=576
Therefore, the original formula =576.
The "plus sign or minus sign" in the formula means that the root sign is 4 = 2, but the multiplication (division) of four plus signs or minus signs is equal to (+).
So all the final operations are positive numbers. Hereby explain.
2. Three root numbers 4 times four root numbers 8 divided by root number 16 times six root numbers 32.
= 12 root number 32/ 16 root number 32 times 6
=2/ root number 16
= 1/2
3. Three root numbers 4 times four root numbers 8 divided by root number 16 times six root numbers 32.
=6*8 root formula 2 divided by 4*24 root formula 2
=576
4. Fill in the blanks with the formula with the root sign:
(1) The lengths of the two right sides of a right triangle are 2 and 3 respectively, so the length of the hypotenuse is
(2) The side length of a square with an area of s is:
(3) When diving platform, the time t (unit: seconds) in the air and the platform height h (unit: meters) satisfy the relationship h = 5t2. If t is expressed by a formula containing h, then t=
5. Calculation problems. Analysis: (1) Find the hypotenuse according to Pythagorean theorem;
(2) The square is obtained by the square area formula;
(3) Transform the formula, square it, and find t. (1) with hypotenuse = =;
(2) Let the side length of a square be A, then a2=S, and get a =;
(3) From the square root of h=5t2, t2= and t= (minus the negative value).
So the answer to this question is:,,.
