Answer:

$\large\boxed{\sqrt{56x^{17}}=2x^8\sqrt{14x}}$

Step-by-step explanation:

$Domain:\ x\geq0\\\\\sqrt{56x^{17}}=\sqrt{4\cdot14\cdot x^{16+1}}\\\\\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=\sqrt{4\cdot14\cdot x^{16}\cdot x^1}\\\\\text{use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\\\=\sqrt4\cdot\sqrt{14}\cdot\sqrt{x^{16}}\cdot\sqrt{x}=2\cdot\sqrt{14}\cdot\sqrt{x^{8\cdot2}}\cdot\sqrt{x}\\\\\text{use}\ (a^n)^m=a^{nm}\\\\=2\cdot\sqrt{14}\cdot\sqrt{(x^8)^2}\cdot\sqrt{x}\\\\\text{use}\ \sqrt{a^2}=a\ \text{for}\ a\geq0\\\\=2\cdot\sqrt{14}\cdot x^8\cdot\sqrt{x}=2x^8\sqrt{14x}$

what is the maximum volume of water a hamster bath can hold with a depth of 1 2/3, a length of 2 1/3 inches, and a width of 2 in

8_murik_8 [283]

The volume is 70/9 or 7 7/9.
=========================================
$\frac{5}{3} \times \frac{7}{3} \times \frac{2}{1} = \frac{70}{9}$
$\frac{70}{9} = 7 \frac{7}{9}$
$l \times w \times h = v$

If you save three pennies on January 1, six pennies on January 2, nine pennies on January 3, and continue this pattern for one y

lbvjy [14]

This is an arithmetic series with first term a1 = 3 and common difference = 3

Sum after 365 days = (365/2)[ 2*3 + (365-1)*3]

= 200,385 pennies = $2003.85 Answer
