How to compare the size of 2 to the 35th power, 5 to the 15th power, and 11 to the 10th power

How to compare the size of 2 to the 35th power, 5 to the 15th power, and 11 to the 10th power

A = 35th power of 2 = (7th power of 2) 5th power of 128
B = the 15th power of 5 = (the 3rd power of 5) = the 5th power of 125
C = 10 power of 11 = (2 power of 11) 5 power of 121

Find the function f (x) = under the root sign (X & # 178; + 1) + under the root sign [(4-x) &# 178; + 4]
To use the method of combining numbers and shapes, in short, remember to bring a graph,

F (x) = √ [(x-0) & #178; + (0 + 1) & #178;] + √ [(x-4) & #178; + (0-2) & #178;] so if it is the sum of distances from a point P (x, 0) to a (0, - 1) and B (4,2) on the X axis, then it is obvious that APB is collinear and P is between AB, the minimum value of PA + Pb is | ab | so the minimum value is √ [(0-4) & #178; + (- 2-2) & #178;] = 5

I have a freezer with an input power of 90W. The energy saving label says (kWh / 24h) 0.64. The input power of the other is 220W. What is the power consumption?

220 / 90 = x / 0.64
Power consumption 1.56kwh/24h

Calculation: 1 / 100 + 2 / 100 + 99 / 100=

1 / 100 + 2 / 100 +. 99 / 100
=1/100×（1+2+3+…… +99）
=1/100×（1+99）×99÷2
=99/2

The bedroom of 10 square meters is equipped with white energy-saving lamp. How many watts is good? (3 light bulbs can be installed)
I have some hesitation between 3W and 5W. I hope you can give me more opinions

If you want to light up, install a 5-watt one
If you want to darken it, install a 3-watt one, and the white one should be similar to the 5-watt one
Generally, the bedrooms are equipped with warm colors. If you want to choose, you can also install one 5-watt and two 3-watt warm lights

What is 0.625:25 out of 27

0.625:25/27
=5/8:25/27
=5*27:8*25
=27:40
=27/40

The calculation question 3.4 × 7.5 + 34 × 0.25 3.66 × 0.8 + 0.34 × 0.8-0.8 is calculated by the fifth grade calculation method, and is calculated by the ladder equation
It's urgent! We need to use a simple method to calculate

3.4×7.5+34×0.25
=3.4×7.5+3.4×10×0.25
=3.4×7.5+3.4×2.5
=3.4×(7.5+2.5)
=3.4×10
=34
3.66×0.8+0.34×0.8-0.8
=(3.66+0.34-1)×0.8
=3×0.8
=2.4

As shown in the figure, the power supply voltage does not change. When the key K is closed, the indication change of ammeter and voltmeter in the circuit is ()
A. The number of amperes becomes larger and the number of volts becomes larger B. the number of amperes becomes smaller and the number of volts becomes smaller C. the number of amperes becomes smaller and the number of volts becomes larger D. the number of amperes becomes larger and the number of volts becomes smaller

The circuit diagram shows that: (1) before the key K is closed, the resistance R1 and R2 are connected in series, and the voltmeter measures the voltage U2 at both ends of the resistance R2, and U2 is less than the power supply voltage U. as shown in Figure 1, after the key K is closed, the resistance R1 is short circuited, and only the resistance R2 is connected to the circuit, and the voltmeter measures the power supply voltage u, so the indication of the voltmeter becomes larger

5.6 * 3 / 8 * (- 1 / 7)

5.6 * 3 / 8 * (- 1 / 7) = - 5.6 * 3 / 8 * 1 / 7
=-0.3
