Question

calculate. (2×10^8)(3×10^5) write your answer in scientific notation.

Explanation:

Step1: Multiply the coefficients

$2\times3 = 6$

Step2: Multiply the powers of 10

$10^{8}\times10^{5}=10^{8 + 5}=10^{13}$ (using the rule $a^{m}\times a^{n}=a^{m + n}$)

Step3: Combine the results

$6\times10^{13}$

Answer:

$6\times10^{13}$
