Step-by-step explanation:
(3 x 10^5) x (4 x 10^2) =
(3×4) × 10^(5+2) =
12 × 10^7 or
1,2 × 10^8
Answer:
[tex]{ \tt{(3 \times {10}^{5} ) \times (4 \times {10}^{2}) }} \\ \\ = { \tt{(3 \times 4) \times (10 {}^{5} \times {10}^{2} )}} \\ \\ = { \tt{12 \times {10}^{(5 + 2)} }} \\ \\ = { \tt{12 \times {10}^{7} }} \\ \\ { \boxed{ \tt{120000000}}}[/tex]
