Question

$(5 \times 10 {}^{6}) + (8.4 \times 10 {}^{3} )$
​

Answer 1

Answer:

5008400 or

$5.0084\cdot 10^{6}$

Step-by-step explanation:

$(5\cdot 10^{6})+(8.4\cdot 10^{3}) = 5\cdot 10^{6} + 8.4\cdot 10^{3}$

$5\cdot 10^{6} = 5000000\\8.4\cdot 10^{3} = 8400$

$5000000 + 8400=5008400$

$5008400 = 5.0084\cdot 10^{6}$
