3.82*10^7 + 28,503,921

Answer 1

●First let us express 28503921 in the scientific notation before proceeding with the calculation.

➡️28503921 can be expressed as:-

$2.8503921 \times {10}^{7} = 2.85 \times {10}^{7}$

(rounding off)

Now let us add them:-

${10}^{7} (3.82 + 2.86)$

$6.68 \times {10}^{7}$
