For this case we must simplify the following expression:7 (\sqrt [3] {2x}) - 3 (\sqrt [3] {16x}) - 3 (\sqrt [3] {8x})

We rewrite:

16x = 2 ^ 3 * 2x\\8x = 2 ^ 3 * x

We rewrite the expression:

7 (\sqrt [3] {2x}) - 3 (\sqrt [3] {2 ^ 3 * 2x}) - 3 (\sqrt [3] {2 ^ 3 * x}) =

By definition of properties of powers and roots we have:

\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}

Then, taking the terms of the radical:

7 (\sqrt [3] {2x}) - 3 (2 \sqrt [3] {2x}) - 3 (2 \sqrt [3] {x}) =\\7 \sqrt [3] {2x} -6 \sqrt [3] {2x} -6 \sqrt [3] {x} =

We add similar terms:

\sqrt [3] {2x} -6 \sqrt [3] {x}

Answer:

Option C

sveta [45]
I’m sorry. But none of your choices are correct. The correct answer would be 3 and 4. Further more explaining= 3+ 2 times 4 is 24. 2x= 4. That equals 8 and 3 times 8 is 24
