32 base 4
Base = x + 4 Altitude = 4*base = 4*(x+4) Area = 0.5*base*altitude = 0.5*(x+4)*4*(x+4) = 2*(x+4)2
121 in base 4 = 16 + 8 + 1 (base ten) = 2584 in base 16 = 128 + 4 (base ten) = 132132 + 25 = 157(base 10) = 9D (base 16) = 2131 (base 4)
4 x 4 = 31 in base 5
4 is the base, 3 is the exponent. Answer = 4 to power 3 = 64
