Find x such that 3^x = 27 mod 32 (b)
gregori [183]

Answer:

The value of x is 11.

Step-by-step explanation:

Consider the provided information.

It is given that 3^x = 27 mod\ 32

We know that:

3^4=81

Now if we divide the number 81 with 32 it will gives us remainder 17.

This can be written as:

3^4\equiv 17(mod\ 32)

Now use the property: a^n\equiv b^n(mod\ m)

(3^4)^2\equiv 17^2(mod\ 32)

17²=289, if we divide 289 with 32 it will gives us remainder 1, thus.

3^8\equiv 1(mod\ 32)

Multiply both the sides by 3³.

3^8\times 3^3\equiv 3^3(mod\ 32)

3^{11}\equiv 27(mod\ 32)

Hence, the value of x is 11.

Ivahew [28]

Area of circle: A=pi×r². This area coresponds to 360degrees, or 2×pi radians.

2×pi ....... pi×r²

t radians....x

where t=2.75rads

Area of t: x=pi×r²×t/2/pi=r²×t/2

Area of t: 3²×2.75/2=9×2.75/2=12.375

Answer: the area of 2.75 radians is 12.375
