Step-by-step explanation:
step1. 5 multiply by 10 power 4 is equal to 50000
step2. 2.5 multiply by 10 power 2 is equal to 250
final step Add up step1 and 2 to have 50250 i.e 50000+250= 50250
Answer: 2000000
10^4 times 5 times 10^2 =10^6 times 5
5 times 10^6= 5000000
5000000/2.5
=2000000
2+2=4 so now its 4/4*10. 4*10 is 40 so now its 4/40. Dividing both sides by 4 will get you the simplest form 1/10
