Ok so i know how to multiply in scientific notation but this one is so hard. pls and pls show your work. (5.7 x 10^7)+(1.8 x 10^8)+(1.5 x 10^8) youu

Basically if you have an exponent at the end of a 10,  , then in the end the extended notation is going to have 7 zeros. So it'll be 10000000. Then you multiply whats in the rest of the equation together. There's the beginning :) I hope it helps.

The coordinates of point a right now is (-3,-1) you have to multiply these coordinates by a factor of 2 to get (-6,-2)
