<span> |2x − 5| − 2 = 3
</span><span>1) |2x − 5|  = 3 +2
2)</span><span> |2x − 5| = 5  
3) 2x-5 = 5, or 2x-5= -5
4)2x=10, or 2x=0
5) x = 5 , or x = 0

Check:
</span> |2x − 5| − 2 = 3
 |2*5− 5| − 2 = 3 or  |2*0 − 5| − 2 = 3
|5|-2=3               or   |-5| -2 =3
3=3 (true)           or    3=3 (true)

All steps are correct.

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}
