320x is an integer under the root sign of degree 3. Find the minimum integer value of X

320x is an integer under the root sign of degree 3. Find the minimum integer value of X

320 under the third root is 4 * 5 under the third root, so x = 25 is the minimum

It is known that ab = 1, M = a + 1 / A + B + 1 / B, n = a + 1 / 1 + B + 1 / 1

Hello, I'm glad to answer for you
Because N-M = 1 / (1 + a) + 1 / (1 + b) - A / (1 + a) - B / (1 + b)
=(1-a)/(1+a) + (1-b)/(1+b)
=(1-a)(1+b)/(1+a)(1+b) + (1-b)(1+a)/(1+b)(1+a)
=(1+b-a-ab+1+a-b-ab)/(1+a)(1+b)
=0
So m = n
Thank you, hope you can add points!

Given m ＞ 1, a = √ (M + 1) - √ m, B = √ m - √ (m-1) for ab size relationship!

A=√(m+1)-√m = 1/ ( √(m+1) + √m )
B=√m-√(m-1) = 1/( √m + √(m-1) )
So a

a> 0, b > 0, M = LG (√ a + √ b) / 2, n = LG √ [(a + b) / 2]
Thank you~

M = LG (√ a + √ b) / 2, n = LG √ [(a + b) / 2] make a difference: M-N = LG (√ a + √ b) / 2 - LG √ [(a + b) / 2] = LG ((√ a + √ b) / 2 / √ [(a + b) / 2]) = LG √ 2 / 2 (√ a + √ b) / √ (a + b))

If z = f (XY, X-Y) = x ^ 2 + y ^ 2, then DZ=
I figured out 2xdx + 2ydy. The answer is 2DX + 2ydy

This is not f (x, y), so it should be for xy and X-Y,

How much fuel does a car need when it travels 5 / 6 km? How many km can a liter of gasoline run

Yes: a car runs 5 / 6 km and consumes 1 / 9 (liter) of fuel
It takes 1 / 9 △ 5 / 6 = 2 / 15 liters to travel 1 km
Driving 5 / 6 △ 1 / 9 = 7.5km with 1 liter oil

What kind of two corners are called adjacent complements

Two corners have a common edge, and the other edge of them is opposite extension to each other

Given that f (z) = u + IV is an analytic function, where u = 2 (x-1) y, find the analytic function f (z) = u + IV (required to be expressed by z) which friend can help me do it
Given that f (z) = u + IV is an analytic function, where u = 2 (x-1) y, find the analytic function f (z) = u + IV (required to be expressed by z). Which friend would you like to help me do the best with process

f(z)=iv/(3-2z)

What is the volume of a piece of ice with a mass of 100g after it turns into water
What is the volume of a piece of ice with a mass of 100g after it turns into water
A bottle can hold 1kg of water. How many kg of alcohol can you hold in this bottle

(1) M ice = m water
Vwater = mwater / pwater = 100g / 1g / cm3 = 100cm3
(1) V wine = V water
M liquor = P liquor * V liquor = P liquor * m water / P water = substitution formula = 0.8kg

What happens when you exceed the speed of light?
If you travel more than 10 times the speed of light, how will the time on board change with that on earth?
Of course, it's theoretical. How many times is not the key. Will the time on the spaceship be reversed?

Please don't mislead children, answer questions carefully
1. Superluminal speed is a concept existing in ideology. In the existing theoretical system, the maximum speed of an object is the speed of light
2. Time can't flow backward, because time is the artificial characterization and description of the object's motion attributes and relative position. If it can flow backward, it must be the attribute of space. Do you understand
3. Of course, when an object moves at or near the speed of light, its internal motion speed will obviously slow down (relatively, of course, it is close to the same speed within the unified system), which means that the problem with you is to go back to the future under possible conditions
