50 points! will award brainliest! i have the scientific notations of 5.8x10^7km and 2.5x10^-3cm and i need them both to be in km. i need a detailed description on how to do that. you must explain in great detail or i will not give brainliest!

converting a number to scientific notation  

in S.N., the decimal point is immediately to the right of the leftmost significant digit  

the number of places that the decimal point must be moved is the size of the exponent of ten  

the direction that the decimal point is moved determines the sign of the exponent  

moving to the left means a positive exponent; to the right means a negative exponent  

58,000,000 becomes 5.8x10^?  

the decimal point moved 9 places to the left. 5.8x10^9  

0.0025 becomes 2.5x10^?  

the decimal point moved 3 places to the right.  2.5x10^-3

y=mx+b
