Question

Which is the BEST estimate for the product of 3.1 * 10⁴?

a) 3.1 × 10²
b) 3.1 × 10⁴
c) 3.1 × 10⁵
d) 3.1 × 10⁶

Answer 1

The best estimate for the product of 3.1 * 10⁴ is 30,000.

Step-by-step explanation:

To estimate the product of 3.1 * 10⁴, we can round 3.1 to 3 and simplify 10⁴ to 10,000. Then we can multiply these two numbers to get our estimate: 3 * 10,000 = 30,000. Therefore, the best estimate for the product of 3.1 * 10⁴ is 30,000.
