<h2>144</h2><h2 />

To do this follow the rule of PEMDAS:

Parenthesis, exponents, multiplication, division, addition, and subtraction.

First, complete the work inside the parenthesis:

(2 x 6) = 12          (3 x 4) = 12

Now your equation should look like this:

12 x 12

The next step in the rule of PEMDAS is exponents. There are no exponents in this equation so skip over that. Now we move onto multiplication.

Now finish the equation by multiplying the 12's together like so:

12 x 12 =  144

Then ignore the rest of the PEMDAS rule since you have already completed the equation.

Hope this helps you and you can use it for future reference. ^w^

What is the cube root of -729a^9b^6?<br> -9a^3b^2<br> -9a^2b^<br> -8a^3b^2<br> -8a^2b^3
timurjin [86]

Answer:

= 9a^3b^2

Step-by-step explanation:

\sqrt[3]{-729a^9b^6} =

= ((-9)^3a^9b^6)^{\frac{1}{3}

= (-9)^{3 \times \frac{1}{3}} \times a^{9 \times \frac{1}{3}} \times b^{6 \times \frac{1}{3}}

= (-9)^{1} \times a^{3} \times b^{2}

= -9a^3b^2

The equation $(x - 7)^2 + (y + 13)^2 = 12$ represents a circle. What is its radius?
miskamm [114]

Answer:

<h3>2√3</h3>

Step-by-step explanation:

The standard equation of a circle is expressed as;

(x-a)²+(y-b)² = r² where;

(a, b) is the center of the circle

r is the radius of the circle

Given the equation (x - 7)^2 + (y + 13)^2 = 12

On comparing;

r² = 12

Take the square root of both sides

√r² = √12

r = √12

r = √4*3

r = 2√3

Hence the radius of the circle is 2√3
