With radical Be more specific (root 5-2 / 5 of root) Radical 48 - radical 3 11 + root 2 / 11

With radical Be more specific (root 5-2 / 5 of root) Radical 48 - radical 3 11 + root 2 / 11

(root 5-2 / 5) 2 = (2 times 5-5 times root 5) 2=
(3 times the root of 5) 2 = 9 / 5
Root number 48 root number 3 = 4 times root number 3 = 3 times root number 3
11 + 2 / 11 root = 11 / 11 (121 + 2 times root 11)

Who can do math problems with roots? Calculation: (- root 3 + root 2) - root 12; quick!

（-√3+√2）-√12=-√3+√2-2√3=-3√3+√2

On the root of the mathematical problem! 1.4 times root number 8 minus 7 times root number 50 =? 2. √ a fourth power + a sixth power times B power 3. We know the value of x = radical 3, y = radical 3 - radical 2, sphere 3 x - 5xy + 3 y

1.4 times root number 8 minus 7 times root number 50 = 8 √ 2-35 √ 2 = - 27 √ 22. √ a fourth power + a sixth power multiplied by B power = √ (a ^ 4 (1 + a A2B?) a √ (a? B ＋ 1) 3. It is known that x = root 3, y = root 3 - root 2, ball 3 x-5xy + 3 y, 3 x-5xy + 3 y = 3 * 3-5 *

Urgent use of radical T = the square of 5t - 16t + 16 (the square of 5t - 16t + 16 is under the root sign) Find the value of T

t=√(5t²-16t+16)
∴t²=5t²-16t+16
∴4t²-16t+16=0
∴t²-4t+4=0
∴(t-2)²=0
∴t=2
This is my conclusion after meditation,
If you can't ask, I will try my best to help you solve it~

Root number mathematics The 2n power root sign "(2x-y) to the power of 2n" = a (a is greater than or equal to 0), 2n + 1 root sign "(x-2y) to the power of 2n + 1" = B, find x + y

The formula of (2x-y) 2n power = a (a is greater than or equal to 0) ① 2n + 1 root sign of (x-2y) 2n + 1 power = B ② the formula of (2x-y) = a (a is greater than or equal to 0) can be simplified as follows: | 2x-y | a (a is greater than or equal to 0), that is, 2x-y = a

Math problem (radical) √(4-2√2) The result should be radical, not simplified

This can't be simplified

Math problem (√ is root) Simplify a √ - 1 / A

-1 / a > 0, so a

A number has two square roots, a + 3 and 2a-15, It is known that the square root of 2m + 2 is positive and negative 4, and the square root of 3M + N + 1 is plus or minus 5. Find the value of M + 2n The first question is what is the number

The first problem: from a + 3 and 2a-15 as the two square roots of a number, | a + 3 | = | 2a-15 |, both sides of the equation are squared at the same time: the square of a + 6A + 9 = 4A - 60A + 225, that is, the square of 3A - 66A + 216 = 0, divided by 3, the square of a - 22a + 72 = 0, that is, (A-4) (A-18) = 0, can be solved to a = 4 or a = 18, when a = 4

Pythagorean theorem. Radical 1. A square ladder is 25m long, leaning against a wall, the bottom of the ladder is 7m away from the wall, and the top of the ladder is 24m away from the ground. (1) if the top of the ladder falls by 4m, then the bottom of the ladder slides in the horizontal direction for several meters, How high was the top of the ladder from the ground 2. Calculation. 6 - √ 3 / 2 - 2 √ 2 / 3 3. Given x + y = 5, xy = 3, find the value of √ y of X + √ X of Y The day after tomorrow, the teacher doesn't understand ._________ _________ 2. Calculation. 6 - √ 3 / 2 - 2 √ 2 / 3 _______ _______ 3. Given x + y = 5, xy = 3, find the value of √ y of X + √ X of Y -I have used this equation to calculate x = 0. Because 24? 2 + 7? 2 = 25 -2. I think I can calculate, but I always think it's not right. Can you give me an answer? Think for yourself -I'm not going to be one of those equations

1. Set the sliding speed x M
Pythagorean theorem (24-x) ^ 2 + (7 + x) ^ 2 = 25 ^ 2
The solution is x = 0 or 17
So the 17 meter drop was established
2. Calculation. 6 - √ 3 / 2-2 √ 2 / 3 = 6-7 root sign 6 / 6
_______ _______
3. Given x + y = 5, xy = 3, find the value of √ y of X + √ X of Y
√ X in y + √ y in x = radical (XY) * (1 / y + 1 / x)
=Root sign (XY) * (x + Y /) / (XY) = radical 3 * 5 / 3 = (5 radical 3) / 3

At the same time, the semicolon is multiplied by the square of (3-radical 5), the denominator becomes (9-5) times (9 + 5), and the numerator is the square of (3-radical-5). The upper and lower semicolons are the same as the numerator. The upper part becomes square, and the lower part becomes {(a + b) - (a-b)} above square expansion
