The expression for which you want to find an equivalent form is:
Answer:
Here there are 3 equivalent expressions:
Explanation:
There are many equivalent forms that you can find, so I will show some of the most important.
The first step that you should do is to put the radicand number (the number inside the root, i.e. 3) as a product of its prime factors. Thus the first equivalent expression is:
Now you can simplify the root index, 4, with the exponent of the radicand, 2, an you get a new equivalent:
Another equivalent form is obtained if you convert the 1/2 index (before the x) into a root index:
The main properties used to find those equivalent expressions are:
And:
11. 6÷5=$1.2 12. 50÷7.90= $6.32 13. 24÷2.95= $8.13 14. 200÷12=$16.6 15. 14.40÷4.5= $3.2 or (4.5÷14.4= 0.3125- Probably not the right answer, I just know it. :)) 16. 22÷2 = $8. Here are your answers! I hope they are right. :)
1) x^2=64 is the same as x=the root of 64 which gives us: (+-)8
2) here you must us pq-formel as:
5m^2-5m=60
5m^2-5m-60=0
(m^2-5m-60)/5=0
m^2-m-12=0
m=0,5(+-) the root of 0,25+12
m=0,5(+-)3,5
m1=0,5+3,5
m2=0,5-3,5
15) x^2=7x
x^2-7x=0 here there is two x, so:
x(x-7)=0
x1=0
x2=7

Here you can only use PQ formula in all the others, just as I did in the question number 2</span>
Answer:
(6 x 5) - (2 x 2)
Step-by-step explanation:
A = Width x Length
Main Square is measured 5 width, 6 length
Missing Square inside is measure 2 width, 2 length.
