If the price of gold went from $460an ounce to $483 an ounce in one week. What was the percent change in the price of gold?

1 answer:

3 0

It was a 5 percent change because if you subtract 460 form 483 you will get 23, then you need to divide 23 by 460. You will get 0.05. You need to multiply that answer by 100 to get 5

What is the following product? ^3 square root 24 times ^3 square root 45

Answer:

$6 \sqrt[3]{5}$

Step-by-step explanation:

For the problem, $\sqrt[3]{24} *\sqrt[3]{45}$ , use rules for simplifying cube roots. Under the operations of multiplication and division, if the roots have the same index (here it is 3) you can combine them.

$\sqrt[3]{24} *\sqrt[3]{45} = \sqrt[3]{24*45}$

You can multiply it out completely, however to simplify after you'll need to pull out perfect cubes. Factor 24 and 45 into any perfect cube factors which multiply to each number. If none are there, then prime factors will do. You can group factors together such as 3*3*3 which is 27 and a perfect cube.

$\sqrt[3]{24*45} =\sqrt[3]{3*8*5*3*3} = 6 \sqrt[3]{5}$
