Answer:
2003₅
Step-by-step explanation:
10111₂ (binary) = 2⁴ + 0³ +2² + 2¹ + 2⁰ = 16+4+2+1 = 23 (decimal)
1011₂ = 2³ + 0² + 2¹ + 2⁰ = 8 + 2 + 1 = 11
23 x 11 = 253 in decimal
To get this converted to base 5, divide repeatedly by 5 and list the remainders in reverse order
253/5 = 50, remainder 3
50/5 = 10, remainder 0
10/5 = 2 remainder 0
2/5 = 0 remainder 2
253 in decimal = 2003₅
