Rewrite in simplest rational exponent form √x • 4√x. Show each step of your process.

Lisa [10]

$First\ step:you\ must\ have\ the\ domain\ (D)\\x\geq0\to D:x\in[0;\ \infty)\\\\Second\ step:use\ \sqrt{a}\cdot\sqrt{a}=\left(\sqrt{a}\right)^2=a\ for\ a\geq0\\\\Solution:\\\sqrt{x}\cdot4\sqrt{x}=4(\sqrt{x})^2=\huge\boxed{4x}$

$or\ other\ method\\\\First\ step:\ use\ \sqrt{x}=x^{\frac{1}{2}}\\\\\sqrt{x}\cdot4\sqrt{x}=x^\frac{1}{2}\cdot4x^{\frac{1}{2}}\\\\Second\ step:\ use\ a^n\cdot a^m=a^{n+m}\\\\x^\frac{1}{2}\cdot4x^{\frac{1}{2}}=4\cdot x^\frac{1}{2}\cdot x^{\frac{1}{2}}=4x^{\frac{1}{2}+\frac{1}{2}}=4x^1=\huge\boxed{4x}$

SpyIntel [72]

Answer:

The correct answer is 9x + 7 y $\geq$ 147 where Ashley works for x hours as lawn mower and y hours as babysitter per week.

Step-by-step explanation:

Ashley works in two different jobs namely mowing lawns and babysitting.

Let Ashley mow lawn for x hours and babysit for y hours in a week.

Ashley's earning for every hour she mow is $ 9. Total earning mowing lawn is $ 9x.

Ashley earns $7 for every hour she babysit. Total earning babysitting is $ 7y.

Total earning per week $ (9x + 7y).

Ashley's earning per week is at least $147.

∴ The required inequality to describe the above case is 9x + 7 y $\geq$ 147.
