just got a 100 on it its B, A, D, B
(5.1 × 10^3) • (3.2 × 10^3)
(5.2×3.2)×(10^3×10^3)
16.32×10^6
But that is not scientific notation. The leading number must be at least 1.0, and less than 10, so you need to shift the decimal point and adjust the exponent:
1.632×10^7
Now do the others the same way.

I hope this helps! :)
Thx guys
Thank y'all 😁😀👏
THE ANSWER IS BAD BI*@H

1. To find the product of (5.1 × 10^3) • (3.2 × 10^3), we multiply the two numbers together.
5.1 × 3.2 = 16.32.
Next, we multiply the powers of 10:
10^3 • 10^3 = 10^(3 + 3) = 10^6.
Therefore, the product is 16.32 × 10^6.
So, the correct answer is "16.32 × 10^6".
2. To find the product of (7.28 × 10^-2) • (9.1 × 10^-2), we multiply the two numbers together.
7.28 × 9.1 = 66.248.
Next, we multiply the powers of 10:
10^-2 • 10^-2 = 10^(-2 + -2) = 10^-4.
Therefore, the product is 66.248 × 10^-4.
So, the correct answer is "66.248 × 10^-4".
3. To find the quotient of (2.965 × 10^7) ÷ (5 × 10^3), we divide the two numbers.
2.965 ÷ 5 = 0.593.
Next, we divide the powers of 10:
10^7 ÷ 10^3 = 10^(7 - 3) = 10^4.
Therefore, the quotient is 0.593 × 10^4.
So, the correct answer is "5.93 × 10^3".
4. To find how much wheat Canada produced, we need to calculate one twenty-fifth of the world production of wheat.
One over twenty-five of 5.2 × 10^8 is found by dividing it by 25.
5.2 × 10^8 ÷ 25 = 2.08 × 10^7.
Therefore, Canada produced about 2.08 × 10^7 metric tons of wheat.
So, the correct answer is "2.08 × 10^7".
