3102 base4 = 3x4^3+ 1x4^2 + 2x1 = 3x64 + 1x16 + 2 = 210 base10
The powers of 2 are 2, 4, 8, 16, 32, 64, 128, 256
210 = 128 + 64 + 16 + 2 = 2^7 + 2^6 + 2^4 + 2^1 = 11010010 base2
A faster method is to each digit in base 4 to two digits in base 2
3 base4 = 11 base2
1 base4 = 01 base2
0 base4 = 00 base2
2 base4 = 10 base2
So 3102 base4 = 11010010 base2
If you wanted to convert base 4 to (say) base 5 you would need the first method and convert to base 10 first

Answer:
3x+2°=65° (vert opp angles)
3x=65°-2°
=63°
x=63÷3
=21
Answer: 2n^2+3n-4
1st differnce is 3, 7, 11, 15
2nd differnce is 4
so its 2n^2
we compare it to teh 2n^2 sequence
2 8 18 32 50
-1 2 9 20 35
difference is 3, 6, 9, 12,15
so it is 3n-4
