Sure, let me help you with these problems!
1. To find the product of (5.1 x 10^3) and (3.2 x 10^3), you simply need to multiply the numbers outside the exponential notation and add the exponents. Multiply 5.1 by 3.2, and you get 16.32. Then, add the exponents 3 + 3, which gives you 6. Therefore, the product in scientific notation is 1.632 x 10^7.
2. Similarly, to find the product of (7.28 x 10^-2) and (9.1 x 10^-2), multiply the numbers (7.28 and 9.1) and add the exponents (-2 + -2). The product of 7.28 and 9.1 is 66.248, and adding -2 and -2 gives you -4. Therefore, the product in scientific notation is 6.6248 x 10^-4.
3. To find the quotient of (2.965 x 10^7) divided by (5 x 10^3), divide the numbers (2.965 by 5) and subtract the exponents (7 - 3). The quotient of 2.965 and 5 is 0.593, and subtracting 3 from 7 gives you 4. So, the quotient in scientific notation is 5.93 x 10^4.
4. Finally, to find the product of (4.0 x 10^-2) and (5.2 x 10^8), multiply the numbers (4.0 and 5.2) and add the exponents (-2 + 8). The product of 4.0 and 5.2 is 20.8, and adding -2 and 8 gives you 6. Therefore, the product in scientific notation is 20.8 x 10^6.
I hope that helps! Let me know if you have any further questions.
