Step-by-step explanation:

well you using exponents so you have to count the zeros and 10 times 8 would be 100,000,000 and 10 to the power of seven would be 1000,000,0 and I think your suppose to multiply that but look where not done yet so you have to multiply 2.25 times 10 to the 7 power which would be 2250000000 and 2.5 times 10 to the 8 power and then you would multiply that and you would get 500,000,000 because you have to add it and if I am wrong than plz tell me and I will fix and and can I get likes and brain list

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
