Answer: OPTION C.

Step-by-step explanation:

According to the Quotient of powers Property, if you divide two numbers whose base is the same, you must rewrite the base and subtract the exponents. Observe:

\frac{a^m}{a^n}=a^{(m-n)}

Notice that "a" is the base and "m" and "n" are the exponents.

Therefore, knowing this property, you can solve the exercise.

Given the following expression:

\frac{3^{15}}{3^3}

You can notice that the base 3 is in the numerator and in the denominator, then you must  apply the Quotient of powers Property and subtract the exponents.

You get that the result is:

=3^{(15-3)}=3^{12}

Which shows a difference of squares?
d1i1m1o1n [39]

Answer:

The equations shows a difference of squares are:

<u>10y²- 4x²</u>   $   <u>6y²- x²</u>

Step-by-step explanation:

the difference of two squares is a squared number subtracted from another squared number, it has the general from Ax² - By²

We will check the options to find which shows a difference of squares.

1) 10y²- 4x²

The expression is similar to the general form, so the equation represents a difference of squares.

It can be factored as (√10 y + 2x )( √10 y - 2x)

2) 6y²- x²

The expression is similar to the general form, so the equation represents a difference of squares.

It can be factored as (√6y + x )( √6y - x)

3) 8x²−40x+25

The expression is not similar to the general form, so the equation does not represent a difference of squares.

4) 64x²-48x+9

The expression is not similar to the general form, so the equation does not represent a difference of squares.

Factor each completely.if non-factorable, write"non-factorable".
Mamont248 [21]
(k+4) (k-4) the numbers have to multiply up to what ever the number is. so the number is 16 and 4 times 4 is 16. also a pluss and minus makes it into a negative number like the equation
