First you need to know some rules 2 numbers that are the same with coefficients divided : you differentiate those coeff
and multyplied :you sum up them

12x^8/3x^3= 4x^8-3=4x^5

20^2x=20^x*20^x

m^5*m^-7=m^5-7=m^-2

Round this number to the nearest million<br><br> 135,458,267

Svet_ta [14]

1,000,000 is million
to round look at hundred thousand place or 100,000
see number before million (after comma)

if it is greater than or equal to 5, add 1 to current value of million and say all after is 0
if less than 5 then leave million value as is and make after 0

135,458,267
hundred thousand value is 4
4<5
135,000,000
