When______ When, the formula x−3+1 5 − x makes sense

When______ When, the formula x−3+1 5 − x makes sense

According to the meaning of the title, we get
x−3≥0
5−x＞0 ，
The solution is 3 ≤ x < 5

When x is divided by X-2 under the root sign, the formula is meaningful in the range of real numbers

X is greater than or equal to 0 and X is not equal to 2

When X -, the root of the formula x-3 + 1 / 5-x of the radical is meaningful

x-3>=0
5-x>0
∴3

2 root 5-root 125 + root 45

Root number 125 = 5 times root number 5
Root number 45 = 3 times root number 5
So the result is 0

If the third power of a is 125 and the third root B is equal to a fifth of a, find the value of a + B

If the third power of a is 125, then a = 5, then the third root B is equal to the fifth, and a is equal to 1, then B = 1
Then a + B = 6

What is the root 0.1875 equal to

From the meaning of the question: convert the decimal 0.1875 to fraction: 3 / 16
So √ 0.1875 = √ (3 / 16) = √ 3 / √ 16 = √ 3 / 4 (1)
So the radical 0.1875 is equal to √ 3 / 4
(1) using √ (A / b) = √ A / √ b)

Root 50 times root 48 divided by root 54

Root 50 times root 48 divided by root 54
=√（50x48÷54）
=√（400/9）
=20/3

Calculate (3 + 2) (2-radical 3) - Radix 12 divided by Radix 3

(3+2)(2-√3)-√12/√3
=5(2-√3)-2√3/√3
=10-5√3-2
=8-5√3
(√3+2)(2-√3)-√12/√3
=4-3-2√3/√3
=1-√3
