What is the remainder of (2^91 x 6^27) divided by 7?

kondaur [170]

$2\equiv2\mod7$
$2^2\equiv4\mod7$
$2^3\equiv8\equiv1\mod7$

$91=3(30)+1$
$\implies2^{91}\equiv(2^3)^{30}\times2^1\equiv1^{30}\times2\equiv2\mod7$

$6\equiv-1\mod7$
$6^2=6\times6\equiv6(-1)\equiv-6\equiv1\mod7$

$27=2(13)+1$
$\implies6^{27}\equiv(6^2)^{13}\times6^1\equiv1^{13}\times6\equiv6\mod7$

$\implies2^{91}\times6^{27}\equiv2\times6\equiv12\equiv5\mod7$

Hi, I need help working this problem out please.

Gnesinka [82]

5(4x-1) = 80

20x - 5 = 80

20x - 5 + 5 = 80 + 5

20x = 85

20x/20 = 85/20

X = 85/20

X = 17/4 if reduced to lowest terms by dividing both the top and bottom number by 5.

In the figure M ab =45 and M cd= 23 what is the value of x?

const2013 [10]

Answer:

34°

Step-by-step explanation:

The measure of vertical angles formed by two chords is equal to one half the sum the measures of the arcs.

In other words, x is the average:

x = (23° + 45°) / 2

x = 34°
