sorry It took so long I was busy :) @alison124

Answer 5

\[ 1.3043835 \times10 ^{5}\]

Answer 6

sry there was a netwrk error :)

open brackets nd get-\[4.3\times 10^5 \times 2.7 \times 10^7 \]
simplify 4.3 x 2.7=11.61 and 10^5 x 10^7=10^12
so we get-
\[11.61 \times 10^\left( 12 \right)\]to write it in scientific notation we put decimal after the 1st place so it wuld be like-\[1.161\times 10 \times 10^\left( 12 \right) =>1.161 \times 10^\left( 13 \right)\]
