Step-by-step explanation:
According to the Order of Operations [GEMS\BOMDAS\PEMDAS etc.], in this case, evaluate everything in grouping symbols first, then evaluate the exponents to avoid confusion:
![\sqrt{(32 + {2}^{3} - 4)} = \sqrt{32 + 8 - 4} = \sqrt{36} = ±6 \\ \\ (17 - 11 + {4}^{2}) \div 11 = (17 - 11 + 16) \div 11 = \\ \\ 22 \div 11 = 2](https://tex.z-dn.net/?f=%5Csqrt%7B%2832%20%2B%20%7B2%7D%5E%7B3%7D%20-%204%29%7D%20%3D%20%5Csqrt%7B32%20%2B%208%20-%204%7D%20%3D%20%5Csqrt%7B36%7D%20%3D%20%C2%B16%20%5C%5C%20%20%5C%5C%20%2817%20-%2011%20%2B%20%7B4%7D%5E%7B2%7D%29%20%5Cdiv%2011%20%3D%20%2817%20-%2011%20%2B%2016%29%20%5Cdiv%2011%20%3D%20%5C%5C%20%20%5C%5C%2022%20%5Cdiv%2011%20%3D%202)

Answer:
The density of the bar of gold is 19.32 grams per cubic centimeter .
Step-by-step explanation:
Formula
![Density = \frac{Mass}{Volume}](https://tex.z-dn.net/?f=Density%20%3D%20%5Cfrac%7BMass%7D%7BVolume%7D)
As given
A bar of gold has a volume of 722 cubic centimeters and weighs 13.949 kilograms.
As 1 kilogram = 1000 gram
Than convert 13.949 kilograms into grams.
13.949 kilograms = 13.949 × 1000 grams
= 13949 grams
Mass = 13949 grams
Volume = 722 cubic centimeter
As put in the formula
![Density = \frac{13949}{722}](https://tex.z-dn.net/?f=Density%20%3D%20%5Cfrac%7B13949%7D%7B722%7D)
Density = 19.32 grams per cubic centimeter (Approx)
Therefore the density of the bar of gold is 19.32 grams per cubic centimeter .
