\[ 38_{16} = 3 \times 16^{1} + 8 \times 16^{0} = 3 \times 16 + 8 \times 1 = 48 + 8 = 56_{10} \)
\[ 75_{8} = 7 \times 8^{1} + 5 \times 8^{0} = 7 \times 8 + 5 \times 1 = 56 + 5 = 61_{10} \)
\[ 110100_{2} = 1 \times 2^{5} + 1 \times 2^{4} + 0 \times 2^{3} + 1 \times 2^{2} + 0 \times 2^{1} + 0 \times 2^{0} \)
\[ = 1 \times 32 + 1 \times 16 + 0 \times 8 + 1 \times 4 + 0 \times 2 + 0 \times 1 \)
