-$\left( 5 \times 10 ^ { 6 } \right) \left( 8 \times 10 ^ { 8 } \right)$
A) $40 \times 10 ^ { 15 }$
B) $4 \times 10 ^ { 14 }$
C) $4 \times 10 ^ { 15 }$
D) $40 \times 10 ^ { 48 }$

Quizplus · Accepted Answer

To multiply numbers in scientific notation, you multiply the two coefficients and add the exponents. So, in this case, we have:
$$\left( 5 \times 10 ^ { 6 } \right) \left( 8 \times 10 ^ { 8 } \right) = 40 \times 10 ^ { 14 }$$
However, we need to put this answer in scientific notation, so we can express it as:
$$4 \times 10 ^ { 15 }$$
Therefore, the answer is C.
