What is ∛2197? Explain how you got your answer.
user100 [1]

Answer:

13

Step-by-step explanation:

We need to write our answer in exponential form. Ask yourself the question, "What times itself 3 times will give you 2197?" Your answer is 13^{3}. This will go inside of your cube root. You now have \sqrt[3]{13^{3} }. Since there's a power of 3 and a cube root, those cancel each other out, and your answer is 13.

A game costs $39.00. But the new special edition version is going to be $56.94. What is the increased percent?
astraxan [27]

Answer:

46%

Step-by-step explanation:

<u>Step 1:  Make an expression</u>

<u />39.00 * x = 56.94

39x = 56.94

<u>Step 2:  Divide both sides by 39</u>

<u />39x / 39 = 56.94 / 39

x = 1.46

<u>Step 3:  Find the percent</u>

<u />1.46 - 1 -> Gives us the increased percent

0.46 * 100

46%

Answer:  46%
