You use the power root function key accessible with the key sequence [SHIFT][X ^]. I am inserting a screen capture from the manual to show you the sequence.

On the third line of the capture (power root) is the key you must press. In the small rectangle to the left of the radical sign you enter the order of the root: 2 for square root, 3 for cube root, 4 for 4th root and son on.

To calculate the decimal log you use the [LOG] key as shown on capture. For natural log (ln), use the [LN] key. The argument (2/3) in your example should be enclosed inside the parentheses.

What is the sum if the quotient of 2/3 and 7/12 is added to 17/14

Proceed step by step.
Quotient of (2/3) by (7/12) =(2/3)/(7/12)=(2/3)*(12/7)=8/7
Sum of 8/7 and 17/14 is 8/7+17/14=16/14+17/14=(33/14)

The initial population of a town is 2800, and it grows with a doubling time of 10 years. Whay wi the population be in 12 years

The population doubles in ten years so the annual growth is the tenth root of two. The growth in twelve years is the annual growth rate raised to the twelfth power.

The tenth root of two is about 1.0718 . That value raised to the twelfth power is about 2.2974 . Multiplied by the initial population of 2800 gives 6433.

I lost my instructions for my Pasta Boat and I don't know what power to use or how much water.

For elbow, bowtie, ziti, rotini, and penee

1 serving -1/2cup -water level at #1
2 servings -1 cup -water level at #1
3 servings - 1 1/2cups - water level 2
4 servings - 2 cups - water level at 4
6 servings - 3 cups - water level at 6
8 servings - 4 cups - water level at 8

cook times based on serving size ( serving size - minutes)

1 - 17
2 - 18
3 - 21
4 - 23
6 - 25
8 - 27

Stir macaroni once halfway through cooking for al dente; for softer pasta, cook several minutes longer.

and just because I couldn't find this online no matter how hard I tried:

For spaghetti, linguine, angel hair and fettuccini

1 serving - 1/2 the handle - water level 1
2 servings- 1 full handle - water level 2
3 servings- 1 1/2 handles - water level 3
4 servings- 2 full handles - water level 4
6 servings- 3 full handles - water level 6
8 servings- 4 full handles - water level 8

cook time servings/minutes

spaghetti - 1/13-14, 2/15-16, 3/16-18, 4/18-20, 6/20-22, 8/22
thin pasta-1/12-13, 2/13-14, 3/15-16, 4/17-18, 6/19-20, 8/21
angel hair- 1/11-12, 2/12-13, 3/13-14, 4/14-15, 6/15-16, 8/17

Pythagorean theorem to find the width along the horizonal

You should checkout Bitesize revision:

http://www.bbc.co.uk/scotland/education/bitesize/standard/mathsI/pythagoras/pythagoras_rev1.shtml

To summarise - Pythagoras works with right angled triangles only (with one 90 degree angle). One side is always bigger than the other two - it's always the one opposite the 90 degrees.

The long side (hypotenuse) times by itself is the same as if you times-ed the other sides by themselves and added them together.

In your question, you're trying to find the across (which you guess as 12?).

The diagonal (14) is opposite the right angle so it's the biggest (and equal to the other two). We'll call across a, we don't know what it is.

14 * 14 = (7.5 * 7.5) + (a * a)

Rearrange:

(14 * 14) - (7.5 * 7.5) = (a * a)

Type that bit on the left into a calculator (you might need to do it in parts - work out 14 * 14 and write it down...). Once you've got the answer you need to use the square root button to find out what a is.
