The

radical number is sometimes called, irrational number. Radical number is inside the specific symbol √. For example, √a is called square root of a, for all value positive of the number a.
According to our case, there are five choices, among these, the numbers which can be called as radical are

3x√x²y , x√xy²,

proof:

3x√x²y = √9x²x²y= √9x²√x²y, and we know that √9x² = 3x, so √9x²√x²y= 3x√x²y

x√xy² =√x²xy² , and we know that √x² = x, so √x²√xy²= x√xy²

Answer from: lesleyy7278

Radicals are irrational numbers and inside the square root the numbers are radical numbers. In the given option the like radicals are option a) and d).

Given :

$2\sqrt{x^2y}$

Radicals are irrational numbers and inside the square root the numbers are radical numbers. In the given option the like radicals are:

a) $3x\sqrt{x^2y}= \sqrt{(3x)^2x^2y}$

So, $\sqrt{(3x)^2}= \sqrt{9x^2} = 3x$

$\sqrt{(3x)^2x^2y} = 3x \sqrt{x^2y}$

Therefore, it is a radical.

b) $-12x\sqrt{x^2y}$

minus sign indicates that it is not a radical.

c) $-2x\sqrt{xy^2}$

minus sign indicates that it is not a radical.

d) $x\sqrt{yx^2}=\sqrt{x^2yx^2}$

So, $\sqrt{(x)^2}= x$

$\sqrt{(x)^2x^2y} = x \sqrt{x^2y}$

Therefore, it is a radical.

e) $-x\sqrt{x^2y^2}$

minus sign indicates that it is not a radical.

step-by-step explanation:

Answer from: Quest

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.
