-5 √ 8 out of 28 * √ 4 out of 3 * √ 56?

-5 √ 8 out of 28 * √ 4 out of 3 * √ 56?


It's hard to play with this. I can't score up and down
I can use it
It's up and down
The above is 8 * 4 * √ 56 √ 56 can be converted into 2 √ 14, which is 64 √ and 64 √ 14
The following is - 5 √ 28 * √ 3 √ 28 turns into 2 √ 7, so that is 10 √ 21
Next, the score becomes about 5 √ 3 to - 32 √ 2. If you want to rationalize the denominator, it will be negative 32 √ 6 / 5



1.43 degrees 20 seconds + 27 degrees 42 seconds 27 minutes


43 degrees 20 seconds + 27 degrees 42 seconds 27 minutes
=70°62‘27’‘
=71°2’27‘’



(53 degrees 27 minutes - 47 degrees 42 minutes 15 seconds) × 2 / 3?


﹙53°27′-47°42′15″﹚×2/3
= (192420 ″ - 171735 ″) × 2 / 3, because it needs to multiply by 2 / 3, some of the values of degrees, minutes and seconds, whether allocated or subtracted before multiplied, cannot be divided by 3, so they are all converted into seconds
=20685″×2/3
=13790″
=229′50″
=3°49′50″

As shown in the figure, Xiao Ming rotates △ ABC around point O to get △ a ′ B ′ C ′, and then erases the edges AC, BC and rotation center O of △ ABC to determine the rotation center
As shown in the figure, Xiao Ming rotates △ ABC around point O to get △ a 'B' C ', where points a', B 'and C' are the corresponding points of a, B and C respectively. Then he erases the edges AC, BC and rotation center O of △ ABC (leaving no trace). He says that he can find the position of rotation center and △ ABC, do you think so? If so, try to determine the position of rotation center O and △ ABC, If not, please give reasons


Yes. Connect AA ', make the vertical bisector of AA', connect BB ', and then make the vertical bisector of BB'. If the two vertical bisectors intersect at point O, then o is the center of rotation. Connect C'0 and extend it one time to point C, and connect ABC, then the triangle is obtained

The denominator of a fraction is five times more than the numerator. If 3 is added to both the numerator and denominator, the value of the fraction is equal to one-third. Find the fraction


Let X be the numerator, then the denominator is (5x + 2)
According to the meaning of the question, (x + 3) / (5x + 2 + 3) = 1 / 3
Eliminate the denominator to get 3x + 9 = 5x + 5
2x=4
x=2
So the score is 2 / 12
If you don't have equations, you can think of it this way
If 3 is added to the numerator and denominator, the score is equal to 1 / 3, then several fractions with 1 / 3 score can be cited
2/6 3/9 4/12 5/15 6/18.
Subtract 3 from the numerator and denominator to see which exactly meets the requirements of the topic
It is found that the 5 / 15 numerator and denominator are exactly in line with the requirements of the topic after subtracting 3
So the original score is 2 / 12
