Answer:
80,000,000
Explanation:
We can rewrite this expression as:
(4 x 10⁵) x (2 x 10²)
To solve this, we multiply first 4 x 2 = 8 and then we multiply the powers of ten using law of exponents:
10⁵x10²= 10₇.
Therefore, the answer is: 8 x 10⁷. If we write it in decimal form we would have:
80,000,000
