Answer: third option:    4( \sqrt[3]{16})^{2x

Explanation:

4( \sqrt[3]{16})^{2x}=4( \sqrt[3]{16^2})^x  =4( \sqrt[3]{4^4} )^x=4(4 \sqrt[3]{4})^x


I used 16^2 = 4^4

Later, I used 4^4 = 4^3 . 4

None of the given answers are correct. We can check that fairly quickly:
4\sqrt[3]{4}=\sqrt[3]{4^4}=\sqrt[3]{4}=\sqrt[3]{256}
Now let's do the same thing for given answers:
a) 2\sqrt[3]{16}=\sqrt[3]{8\cdot 16}=\sqrt[3]{128}\\
b) 2\sqrt[3]{64}=\sqrt[3]{8\cdot 64}=\sqrt[3]{512}\\

I don't have to continute, it's pretty obvious that answers C and D are wrong (notice we multiply by 4 and on top of that we square the third root).

F(x) = (x + 1)(x - 3)(x - 4)
Vladimir [108]

Answer:

f(x)  x^3 - 2x^2 + 5x + 12

Step-by-step explanation:

Next time please share the goal.  I'm guessing your intent was to multiply out the given function.

f(x) = (x^2 + x - 3x - 3)(x - 4), or

      = (x^2 - 2x - 3)(x - 4)

Now apply the distributive property of multiplication:

f(x) = x^3 - 4x^2 - 2x^2 + 8x - 3x + 12, or

      = x^3 - x^2(4 - 2) + x(5) + 12, or

f(x)  x^3 - 2x^2 + 5x + 12

Convert the number to standard form.<br><br> 8.71 xx10^(12)
ExtremeBDS [4]

8.71 xx10^(12)

The exponent is a positive number. This means the decimal point moves to the right by  the number of the exponent.

There are two digits to the right of the decimal point, so to move the decimal 12 places, you would need to add 10 zeros.

8.71 x 10^12 becomes 8,710,000,000,000.
