Question

What is (5.2 × 10^2) × (1.2 × 10^4)?

Answer 1

62400000

Answer 2

You need to learn to do these yourself.

Answer 3

6240000

Answer 4

5200 x 12000=?

Answer 5

Multiply the number parts together.
Then multiply the powers of 10 together (by adding the exponents).
Then if the new number part is not greater than of equal to one but less than 10, you need to adjust the result.

Answer 6

so its D?

Answer 7

\((5.2 × 10^2) × (1.2 × 10^4)\)

\(=(5.2 \times 1.2) \times (10^2 \times 10^4) \)

\(= 6.24 \times 10^{2 + 4} \)

\(= 6.24 \times 10^6\)

Since 6.24 is greater than or equal to 1 but less than 10, it's acceptable, and that is the final result.

Answer 8

Correct, the answer is D.
