test yourself! practice tool\nfind the sum. write your answer in scientific notation, with the decimal to the nearest thousandth.\n$(1.37\times 10^{12})+(23.47\times 10^{14})$

Answer

Explanation:

Step1: Rewrite numbers with same exponent

Rewrite $1.37\times 10^{12}$ as $0.0137\times 10^{14}$.

Step2: Add the coefficients

$(0.0137 + 23.47)\times10^{14}=23.4837\times 10^{14}$.

Step3: Convert to proper scientific - notation

$23.4837\times 10^{14}=2.34837\times 10^{15}$. Rounding to the nearest thousandth, we get $2.348\times 10^{15}$.

Answer:

$2.348\times 10^{15}$
