A non zero real number could be written as a/1.
When this gets reversed to be 1/a, it is the multiplicative inverse.
Well the square root of a number is a number times its self equaling the number you're getting the square root of. For example:
<span>√ 25
</span>
To get sqrt of 25 we need to find a number times its self that equals 25. Lets try 8.
8 x 8 = 64
Well thats much too high, We'll try a lower number.
4 x 4 = 16
Just a little higher.
5 x 5 = 25
Since 5 times itself equals 25 that makes it the sqrt.
So, the √ 25 is 5.
Answer:
x= 5.6
Step-by-step explanation:
we will need to put the information we currently have into an equation:
10•2•x= 112
then multiply 10•2 which equals 20...then the equation wil turn out like this:
20•x=112
now you will isolate the x... but how?? dividing 20 by itslef.. cancelling it out, and if you do one thing to the other side of the equation, you have to do it to the other...
20/20•x=112/20
you will end up with x= 122/20
you can use a calculator for this step, but to practice long division... (check the screen shot thingie)
hope this helped !! ^^
Hey there!
"What ratio forms a proportion with ?"
- (for the decimal)
But in order for you to solve this particular equation you'd have to go in with two (like multiplying by two)
Your result:
Good luck on your assignment and enjoy your day!

Answer:
2. 12.08
3. 7.74
Step-by-step explanation:
a squared + b squared = c squared
2. 5 squared = 25, 11 squared = 121, 25 + 121 = 146, the squre root of 146 is 12.08
3.19 squared = 361, 421 - 361 = 60 60 squared = 7.74
