A-P-E-X QUIZ
Answer: <u>Irrational </u>
It's irrational because of how 37 comes out of the square root.
For example:
The square root of 64 comes out to 8, which is a whole number. But 37, comes out as an integer and a decimal.
3ˣ (x² - 3)
Basically, just multiply everything together.
Step 1 : 3x × x² = 3x³ because when multiplying exponents, all you're really doing is adding them on top. So, x + 2x = 3x! But, they are exponents, so you get 3x³.
Step 2 : 3x ˣ × (-3) = -9ˣ
Now, our new question is : 3x³ - 9x
You wouldn't simplify this because x³ is NOT the same as x.
