Answer:

The answer should be 15.

Step-by-step explanation:

$\sqrt[3]{125}$ Factor 125 = $5^{2}$ x 5. Rewrite the square root of the product $\sqrt{5^{2}X5 }$ as the product of square roots. $\sqrt{5^{2} }$ $\sqrt{5}$ . Take the square root of $5^{2}$ .

$3$ x $\sqrt[5]{5}$ Multiply 3 and 5 to get 15.

$\sqrt[15]{5}$

Find the dimensions of the rectangle with area 289 square inches that has minimum perimeter, and then find the minimum perimeter

nalin [4]

<span>To minimize the perimeter you should always have a square.
sqrt(289) = 17
The dimensions should be 17 X 17

To see , try starting at length 1, and gradually increase the length.
The height decreases at a faster rate than the length increases, up until you reach a square.

Or if you want to use algebra, Say the width is 17-x
Then the length is 289/(17-x)

Now, this is bigger than 17+x, as shown here:
289/(17-x) > 17+x
289 > 289 - x^2
which is true.
so the perimeter would be bigger than 2 * (17- x + 17 + x) = 2 * (2 * 17) = 4 * 17

Again, the dimensions should be a square. 17 X 17.</span>
