Answer:

$6(3c-d)$ or $3(6c - 2d)$

Step-by-step explanation:

Step 1: Factor out the GCF

The GCF for 18c and 6d is just the number 6.

$18c - 6d$

$6(3c - d)$

Or... you can pull out a 3

$18c-6d$

$3(6c-2d)$

Answer: $6(3c-d)$ or $3(6c - 2d)$

(2³)² solve this problem

max2010maxim [7]

Answer:

$(2^3)^2 = 64$

Step-by-step explanation:

Option 1:

Using the following rule:

$(a^n)^m = a^{nm}$

Put in our expression,

a = 2

n = 3

m = 2

$(a^n)^m = a^{nm}$

$(2^3)^2 = 2^{3*2}=2^6=64$

Option 2:

Using the following rule:

$a^n * a^m = a^{n+m}$

Since our expression is the same as multiplying 2³ with itself, we can write it as a multiplication.

$(2^3)^2 = 2^3 * 2^3$

If we compare this with $a^n * a^m$ , we can see that

a = 2

n = 3

m = 3 (in this case, n and m are equal)

$a^n*a^m = a^{n+m}$

$2^3*2^3 = 2^{3+3} = 2^6 = 64$

Answer: $(2^3)^2 = 64$

Explain the difference between a square pyramid and a square prism.

Maslowich

The square pyramid looks exactly how it sounds. The base of the shape is a square and has 4 isosceles triangles that meet at a point. The square prism is like a 3D rectangle. It has 4 rectangles and 2 squares to close the shape.
Hope this helped.
