Question

(5.2x10^6)*(3.8x10^4)
use scientific notation to multiply, express in scientific notation, retain all nonzero decimal places

Answer 1

so, first you want to multiply the 1st 1 by 10 : and you would get, (52 x 10^5)

then you would also multiply the 2nd one by ten : (38 x 10^3)

so then if you multiply them together, you would multiply 38 x 52 and then add the exponents : (1,976 x 10^8)

if you are supposed to place that in scientific notation, your answer would be (1.976 x 10^11)
