I've been learning about square roots, and perfect-squares. But I'm still a little confused as to how you find a perfect-square. If someone could just describe to me how, then it might give me a greater advantage on an assignment that I'm stuck on.

Question

anonymous · Answer

A perfect square is the product of a rational number multiplied by itself

anonymous · Answer

So 4 9 64 are all Perfect squares (There are more) because they are a rational number times itself

anonymous · Answer

So if I were on an assignment that gave me someone elses work, and asked me to correct it, and they had to round the number 38 to the nearest 10th, they used the numbers 36 and 34 as the perfect-square numbers. Are those two numbers in fact actual perfect-squares?

anonymous · Answer

Cause i would think so. Right?

anonymous · Answer

Are they the product of a rational(whole) number multiplied by itself?

anonymous · Answer

Yeah

anonymous · Answer

Wait, not entirly

anonymous · Answer

Why?

anonymous · Answer

I don't think that 34 is.

anonymous · Answer

You are correct it is not

anonymous · Answer

It doesn't have a rational number that is multiplied by itself that can make it.

anonymous · Answer

If it doesnt then it isnt a Perfect square

anonymous · Answer

Okay. I get now! Thank you for your help. I think I know how to find the other perfect-square to use now. ^_^

anonymous · Answer

Sorry my explanation of rational numbers was wrong. A Rational Number is a real number that can be written as a simple fraction (i.e. as a ratio)

anonymous · Answer

Oh.

anonymous · Answer

Yeah i got it mixed up with another term

anonymous · Answer

Then what do I do? Not to put it all on you. But i swear i am one of those people who need things explained to me in a certain way. My lesson doesn't do it very well. lol

anonymous · Answer

What grade is this for?

anonymous · Answer

9th

anonymous · Answer

Things like 5 are rational because they can be written like 5/1 a simple fraction things like the square root of 2 are not because they cannot be made as a simple fraction. Still need explaining?

anonymous · Answer

anonymous · Answer
