select all that apply.

3 to the power of 12
7 to the power of 9

27.(21)⁹

Step-by-step explanation:

Given: 3¹² . 7⁹

⇒ 3⁹.3³.7⁹  = (3.7)⁹.3³

Because, (a.b)ˣ = aˣ . bˣ

Also, aᵇ . aˣ = aᵇ⁺ˣ

So, (3.7)⁹.3³  = 21⁹. 27.

Therefore the given expression is equivalent to  21⁹. 27.

glide reflection.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.

the first one, all those points on the line just make a strait line.
