Can some one teache me the steps to do sqaure root i cant understand it​

Mathematics

avanturin [10]3 years ago

Answer:

It's easy.

Step-by-step explanation:

The square root of something is just the reverse of some squared.

For example, if you do 3 to the power of 2 (3^2) you get 9. now if you reverse that you would do square root. \sqrt{9} would be 3. Think of it like multiplication and division. If you do 10*5 you get 50. All you have to do is reverse it after that  50/5 = 10. See.

The only difference it square(2) root and squared(2) are only with the number 2. Meaning you can't do 3 to the power of 3 (3^3) and expect to square root it to get the reverse. For example, 3 to the power of 3 (3^3) is 27. But the square root of 27 is NOT 3, it is 5.2

You get it?

Which inequality is graphed on the number line shown?
bearhunter [10]
The graph is to the left of -3, so it's < or ≤.
The circle is filled in so -3 also satisfies the inequality, so it's ≤.
The answer is B. x≤-3.

The intensity, or loudness, of a sound can be measured in decibels (dB), according to the equation I (d B) = 10 log left-bracket
laila [671]

Answer:

<h2>The intensity in decibel is 320 decibel </h2>

Step-by-step explanation:

Given the intensity, or loudness, of a sound  measured in decibels (dB), according to the equation I (dB)= 10log(\frac{I}{Io} ) where;

I is the intensity of a given sound and

Io is the threshold of hearing intensity

To get I(dB) when I=10^{32} Io

We will substitute the value of I = I=10^{32} Io into the equation above to have;

I (dB)= 10log(\frac{10^{32}Io }{Io} )\\I(dB)=10log10^{32}\\ I(dB)=32*10log10\\

Since log10 = 1;

I(dB)=32*10(1)\\I(dB)=320

The intensity in decibel is 320 decibel

7x-2(x+5)=5(5x+9) someone please help me
lilavasa [31]
7x - 2x - 10 = 25x + 45
5x - 10 = 25x + 45
5x - 25x = 45 + 10
- 20x = 55
x = -55/20 = -11/4
