Question

Find the product of - 7 x 10(to the power of)5 and 9 x 10(to the power of)4

Answer 1

Question: \[(-7*10^5)*(9*10^4)\]
Make the powers the same (either 4 or 5) and multiply. For example,
\[(-7*10^5)*(.9*10^5)\] would be evaluated by multiplying -7*.9 and attaching the 10^5 to the end of the product
