What is the simplest form of the product cube root4x^2*cube root8x^7

Illusion [34]

Answer:

f(x) = $2^{\frac{5}{3} }x^{3}$ is the simplest expression

Step-by-step explanation:

We are given an expression and we are supposed to find the simplest form of the given expression.

The given expression is

f(x) = $\sqrt[3]{4x^{2} } \times \sqrt[3]{8x^{7} }$

Since the cube root is common we can multiply the quotient inside the radical sign.

f(x) = $\sqrt[3]{32x^{(2+7)} }$

= $\sqrt[3]{32x^{9} }$

= $2^{\frac{5}{3} }\times x^{\frac{9}{3} }$

= $2^{\frac{5}{3} }x^{3}$

f(x) = $2^{\frac{5}{3} }x^{3}$ is the simplest expression

5. Find a counterexample to show that the following con-

Bess [88]

Answer: see below

<u>Step-by-step explanation:</u>

Any value x such that |x| < 1 will make the conjecture false

<em>In simpler words, let x be a fraction between 0 and 1.</em>

One example: Let x = $\dfrac{1}{2}$

Then x⁴ = $\bigg(\dfrac{1}{2}\bigg)^4$

= $\dfrac{1}{16}$

$\dfrac{1}{16}$ < $\dfrac{1}{2}$

so the conjecture is false.
