What is the cube root of 216x18?
Vikentia [17]

Answer:

<u>The correct answer is 15.72 or  6 ∛18</u>

Step-by-step explanation:

Let's calculate the cube root of 216 * 18

∛(216 * 18)

216 = 8 * 27

8 = 2³; 27 = 3³

18 = 9 * 2 or 3² * 2

∛(8 * 27 * 18)

Simplifying:

∛(2³ * 3³ * 3² * 2)

∛(2³ * 3³ * 3² * 2)

2 * 3 ∛(3² * 2

<u>6 * 2.62 = 15.72 or 6 ∛18</u>

mel-nik [20]

Answer:

(7,-11)

Step-by-step explanation:

We are given the rule of: (x,y)\rightarrow(x+3,y-2).

Apply the rule to point P:

(4,-9)\rightarrow(4+3,-9-2)\rightarrow\boxed{(7,-11)}

P' should be (7,-11).

Hope this helps.
