What is the simplified form of the following expression?

ziro4ka [17]

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:

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

Which expression is the same as 2^-3

4vir4ik [10]

Answer:

$\frac{1}{8}$

Step-by-step explanation:

Using the rule of exponents

$a^{-m}$ = $\frac{1}{a^{m} }$ , then

$2^{-3}$ = $\frac{1}{2^{3} }$ = $\frac{1}{8}$
