Just in case anyone was wondering the answers to this lesson like I was here they are, I tried to find them but couldn’t and then decided to use the app photomath Because I’m in a hurry. Anyway here are the answers
1. What is the product of (5.1 x 10³) x (3.2 x 10³)? (Please express your answer I’m scientific notation.)
Answer: B
2.(7.28 x 10⁻︎²) x (9.1 x 10⁻︎²)
Answer: A
Answer to 3 is D
And answer to 4 is B
Sorry I got lazy and didn’t type the rest of the questions just the answers, I got 4/4 aka 100% so this rare the 2020 answers just in case the answers change in the future so different letters
but the biggest mistake was enabling others to cheat.
Kids like me who don’t have anyone to turn to, to help them with things might need this because we don’t have the money to get help, we don’t have a mom or dad who is home 24/7, we don’t have anyone at all to help us, this is only a last resort help. I’d rather cheat then get bad grade bc I can’t get the help I need
I’m just now realizing I made a ton of spelling mistakes 😭✌️
It seems like you already have the answers to the questions. However, it's important to understand how to arrive at those answers rather than simply relying on an app.
For the first question:
1. What is the product of (5.1 x 10³) x (3.2 x 10³)? (Please express your answer in scientific notation.)
To find the product of two numbers in scientific notation, you can multiply the decimal parts and multiply the powers of 10 separately.
In this case:
5.1 x 3.2 = 16.32 (decimal part)
10³ x 10³ = 10^(3+3) = 10⁶ (powers of 10)
So the product is 16.32 x 10⁶, which is the answer in scientific notation.
For the second question:
2. (7.28 x 10⁻²) x (9.1 x 10⁻²)
Again, multiply the decimal parts and the powers of 10 separately.
7.28 x 9.1 = 66.248 (decimal part)
10⁻² x 10⁻² = 10^(-2-2) = 10⁻⁴ (powers of 10)
So the product is 66.248 x 10⁻⁴.
For the third and fourth questions, you didn't provide the questions themselves, so I'm unable to explain how to arrive at the answers. However, you can use the same principles mentioned above to solve them.
It's important to understand the concepts behind the questions and how to solve them manually. While apps like Photomath can provide quick answers, relying on them solely may hinder your understanding of the subject matter.
