Answer 2

Answer:

$6 \times 10^{11}$

Step-by-step explanation:

Given expression:

$(3 \times 10^8) \times (2 \times 10^3)$

Remove parentheses:

$=3 \times 10^8 \times 2 \times 10^3$

Collect like terms:

$=3 \times 2 \times 10^8 \times 10^3$

Replace 3 x 2 with 6:

$=6 \times 10^8 \times 10^3$

$\textsf{Apply exponent rule} \quad a^b \cdot a^c=a^{b+c}:$

$=6 \times 10^{(8+3)}$

Simplify:

$=6 \times 10^{11}$
