The sum of a number and its reciprocal is 65/8. Find the numbers.
djyliett [7]

Answer: 8 and \frac{1}{8}

<u>Step-by-step explanation:</u>

x + \frac{1}{x} = \frac{65}{8}

need to eliminate the denominator:

x(8x) + \frac{1}{x}(8x) = \frac{65}{8}(8x)

8x² + 8 = 65x

8x² - 65x + 8 = 0

(8x -1)(x - 8) = 0

(8x -1) = 0           (x - 8) = 0

x = \frac{1}{8}                      x = 8

Maru [420]

a1 = 54

a2 = (1/3)a1 = (1/3) * 54 = 18

a3 = (1/3)a2 = (1/3) * (1/3)a1 = 18/3 = 6

etc.

y = 54(\dfrac{1}{3})^{x - 1}

Using fermat's little theorem, find the least positive residue of $2^{1000000}$ modulo 17.
torisob [31]
Fermat's little theorem states that
a^p≡a mod p

If we divide both sides by a, then
a^{p-1}≡1 mod p
=>
a^{17-1}≡1 mod 17
a^{16}≡1 mod 17

Rewrite
a^{1000000} mod 17  as
=(a^{16})^{62500} mod 17
and apply Fermat's little theorem
=(1)^{62500} mod 17
=>
=(1) mod 17

So we conclude that
a^{1000000}≡1 mod 17
