Do you mean raise it to the 1/6th power?

Press 1 . 7 7 9 5 5 4 6 8 y^x ( 1 / 6 ) =

y^x is just above the 9 key, / is the divide key.

Press 1 . 7 7 9 5 5 4 6 8 y^x ( 1 / 6 ) =

Enter it almost exactly as your wrote it.

Assuming you're in the AOS mode, press 2 4 8 9 0 . 6 5 * 1 . 0 6 y^x 4 =

If you're in the chain mode, press 2 4 8 9 0 . 6 5 * ( 1 . 0 6 y^x 4 ) =

"y^x" is the key just above the "9" key. "*" is the multiply key, right and above the "9" key.

Using elementary algebria in the **binomial theorem, **I expanded the power **(***x* + *y*)^n into a sum involving terms in the form a x^b y^c. The coefficient of each term is a positive integer, and the sum of the exponents of *x* and *y* in each term is **n**. This is known as binomial coefficients and are none other than combinatorial numbers.

**Combinatorial interpretation:**

Using** binomial coefficient (n over k)** allowed me to choose** ***k* elements from an **n**-element set. This you will see in my calculations on my Ti 89. This also allowed me to use **(x+y)^n** to rewrite as a product. Then I was able to combine like terms to solve for the solution as shown below.

(x+y)^6= (x+y)(x+y)(x+y)(x+y)(x+y)(x+y) = x^6+6x^5y+15x^4y^2+20x^3y^3+15x^2y^4+6xy^5+y^6

**This also follows Newton's generalized binomial theorem:**

**Now to solve using the Ti 89.**

Using

(x+y)^6= (x+y)(x+y)(x+y)(x+y)(x+y)(x+y) = x^6+6x^5y+15x^4y^2+20x^3y^3+15x^2y^4+6xy^5+y^6

**Using sigma notation, and factorials for the combinatorial numbers, here is the binomial theorem:**

**The summation sign is the general term. Each term in the sum will look like that as you will see on my calculator display. Tthe first term having k = 0; then k = 1, k = 2, and so on, up to k = n. **

To extract the roots of orders higher than 2, you can use the universal power key labeled as [Y to x]. if the exponent is an integer 3, 4, 5, 6 etc.

it gives the cube the 4th power, 5th, 6th, etc.

If the exponent is 1/3, 1/4, 1/5, 1/6 you calculate the cubic root, the 4th root and so on.

When you use it to calculate the roots, the radicand (the number the root of which you are calculating) must be positive, otherwise you may get the result as a complex number.

The syntax of the command is value [Y to x] (1/ order of root)

Ex: cube root of 27 is entered as 27 [Y to x] (1/3)

it gives the cube the 4th power, 5th, 6th, etc.

How about using the powers of 10?

5 000 000 = 5*10^6

8000 =8*10³

5 000 000 *8 000 =5*8*10^(6+3)= 40*10^9=4*10^10

The power of 10 key is the one labeled x10 to the X, between the dot and Ans. It is in the middle of the bottom row of keys.

5 000 000 = 5*10^6

8000 =8*10³

5 000 000 *8 000 =5*8*10^(6+3)= 40*10^9=4*10^10

If you want to find 5 to the power of 6 (5^6)

you hit the 5 button, then the button that says yx ( the x is in the exponent spot) then the 6 so it will looks like this 5^6 then press enter to get the answer...hope that helps!
