Multiplication in GF(24 ): Compute A(x)B(x) mod P(x) in GF(24 ) using the irreducible polynomial P(x) = x 4 + x + 1, where A(x)
tankabanditka [31]

Answer:

Step-by-step explanation:

hello,

i advice you check the question again if it is GF(2^{4}) or GF(24). i believe the question should rather be in this form;

multiplication in GF(2^{4}): Compute A(x)B(x) mod P(x) = x^{4} + x+1, where A(x)=x^{2}+1, and B(x)=x^{3} + x+1.

i will solve the above question and i believe with this you will be able to solve any related problem.

A(x)B(x)=(x^{2} +1) (x^{3}+x+1) mod (x^{4}+x+1  ) = (x^{5} +x^{3}+x^{2}  ) + (x^{3}+x+1  ) mod (x^{4} + x+1 )

= x^{5}+2x^{3} +x^{2}  + x + 1 mod(x^{4}+x+1  )

=2x^{2} +1

please note that the division by the modulus above we used

\frac{x^{5}+2x^{3}+x^{2} +1  }{x^{4}+x+1}= x+\frac{2x^{3} +1}{x^{4}+x+1}

Does any one know the answer
gregori [183]

Answer:

Step-by-step explanation:

Solve for x=0 and x=1

y(0)=2(3^0)=2(1)=2 so (0,2) is a point.

y(1)=2(3^1)=2(3)=6 so (1,6) is a point.

Only graph B has those two points.

Step-by-step explanation:

soh= sin opposite/hypotenuse

sin (65°) 5/x

* x *x

x* (sin 65°)= 5

x (0.906308) =5

÷0.906308 = ÷0.906308

x≈ 5.51689

Derivative of (a^x/Log a)?​
Zolol [24]
<h2>\large\bold{\underline{\underline{To \: \:  Differentive:-}}}</h2>

\sf{\dfrac{a^x}{log(a)} }

<h3>(OR)</h3>

\sf{\dfrac{a^x}{ln(a)} }

<h2>\large\bold{\underline{\underline{Solution:-}}}</h2>

\sf{Let\ y=\dfrac{a^x}{ln(a)} }

\sf{=\dfrac{d}{dx}\bigg[\dfrac{a^x}{ln(a)}  \bigg] }

<h3>(Linear differentiation)</h3>

\sf{=\dfrac{1}{ln(a)}.\dfrac{d}{dx}(a^x)  }

\sf{=\dfrac{ln(a)a^x}{ln(a)} }

\boxed{\sf{=a^x}}

<h2>\large\bold{\underline{\underline{Applied:-}}}</h2>

<h3>✭ Linear differentiation</h3>

→ \sf{[a.b(x)+c.d(x)]'=a.b'(x)+c.d'(x)}

<h3>✭ Exponential function rule</h3>

→ \sf{(a^x)'=ln(a).a^x}
