what are 3 non-equivalent fractions with values between the square root of 56 and the square root of 58

Answers

square root of 56 = 7.483314774
square root of 58 = 7.615773106

so we just need to come up with fractions that are between about 7.4833 and 7.6158

7.5 = 7 1/2 or 15/2
7.55 = 7 11/20  or 151/20
7.6 = 7 3/5  or  38/5

15/2
151/20
38/5
are your fractions

*Note: there are many other possible answers, I was just exemplifying a few.
√(56) \approx7.48\n√(58) \approx7.62

So these fraction can be:
7.5=7(5)/(10)=7(1)/(2)=(15)/(2)\n7.56=7(56)/(100)=7(14)/(25)=(189)/(25)\n7.6=7(6)/(10)=7(3)/(5)=(38)/(5)

Which equation finds the area of a square with a side length of 5n4 units?

Answers

Answer:

25n^8

Step-by-step explanation:

Area of a square is length×length

Length=5n^4

Area=5n^4×5n^4

=(5×5)(n^4+4)

=(25)(n^8)

=25n^8

So the area of a square is 25n^8

The answer is to this question is 25n^8
