Answer 2

Hello mate here is your answer.

(5000)5=3.125×10k
=>(5×10³)5=3.125×10k
=>5(5raised to its power)×10(15)=3.125×10k
=>5(5in the power)×(5×2)15=3.125×10k
=>5(5 in its power)×5(15 in its power)×2(12in its power)=3.125×10k
=>5(20 in its power)×2(15in it's power)=3125/100×10k
=>100²(50²ⁿ×2(15power))=3125×10k
=>(10³×5(20power)(10³×2(15power)=3125×100k
=>(5³×2³×5(20power)(5³×2³×2(15power)=5(5power)×10k
=>5(23power)×2³×5³×2(18power)-5(5power)×10k
=>5(26squared)×2(21squared)/55-10k
=>5(21power)×2(21power)10k
=>10(21power)=10k
=>k=2

Hope it helps you.
