Answer:

\sf   \sqrt{3}

Step-by-step explanation:

\sf =  \frac{3}{ \sqrt{3} }

\sf =  \frac{3}{ \sqrt{3} }  \times  \frac{ \sqrt{3} }{ \sqrt{3} }

\sf =  \frac{3 \sqrt{3} }{( \sqrt{3} \times  \sqrt{3})  }

\sf =  \frac{3 \sqrt{3} }{3}

\sf =  \frac{ \cancel{3} \sqrt{3} }{ \cancel3}

\sf =  \sqrt{3}

<h2>>> Answer </h2>

__________

\:

\frac{3}{ \sqrt{3} }  = ...

=  \frac{3}{ \sqrt{3} }  \times  \frac{ \sqrt{3} }{ \sqrt{3} }

=  \frac{3 \sqrt{3} }{( \sqrt{3}) {}^{2}  }

=  \frac{3 \sqrt{3} }{3}

=  \bold {\sqrt{3} }

Which of the following statements regarding the expansion of (x + y)^n are correct?
kompoz [17]

Answer:

A, B and D are true statements.

Step-by-step explanation:

We are given a binomial expansion

(x+y)^n=^nC_0x^ny^0+^nC_1x^{n-1}y^1+^nC_2x^{n-2}y^2+...........+^nC_nx^0y^n

(x+y)^n=x^n+nx^{n-1}y+^nC_2x^{n-2}y^2+...........nxy^{n-1}+y^n

Now we will check each option

Option A: The coefficients of x^n and y^n both equal 1.

If we see first and last term of the expansion, This statement is true.

Option B: For any term x^ay^b in the expansion, a + b = n.

Let we take 3rd term of expansion ^nC_2x^{n-2}y^2

Here, a=n-2 and b=2

If we do  a+b = n-2+2=n

a+b=n is true statement.

Option C: For any term x^ay^b in the expansion, a - b = n.

Let we take 3rd term of expansion ^nC_2x^{n-2}y^2

Here, a=n-2 and b=2

If we do  a-b = n-2-2=n-4≠n

a-b=n is false statement.

Option D: The coefficients of x^ay^b and x^by^a are equal.

If we take second term from beginning and last of the expansion.

\text{Coefficient From beginning } nx^{n-1}y=n

\text{From last } nxy^{n-1}=n

This statement true.

Solve for x what is -2x-4&lt;10
tino4ka555 [31]

the answer is x is greater then -7

to find this add 4 to each side

then divide by -2.

since you divided both sides by a negative the symbol flips and you get x is greater then -7

Dedi had a combination lock.To open the lock he started at 37.He made 3 half turns clockwise and 3 quarter turns anticlockwise
Lerok [7]
Turning clockwise means the number increase, and counterclockwise means the number decreases

Therefore your answer is 37 + (3*1/2)-(3*1/4)

= 37.75

Hope this helped :)
