7.5 x 10^1
To write the number 33,400 in scientific notation, you first need to express it as a number between 1 and 10 multiplied by a power of 10. This can be done by moving the decimal point four places to the left, resulting in 3.34. Therefore, 33,400 in scientific notation is written as (3.34 \times 10^4).
7.59
That system makes it much easier to write the numbers, remember them, tell them to others, and notice mistakes when they're written wrong.
First person singular of the verb "usar". "Uso". You can use the personal pronoun "yo", but it is not really necessary.
It is not necessary to capitalize the word "yo".
Yes, response pads are typically needed for a yo-yo to provide the necessary friction for the yo-yo to return to the hand when thrown. These pads help create the grip on the inner edge of the yo-yo's response system. While some advanced yo-yos use different mechanisms, response pads are common in many standard models for optimal performance.

It means, "I have the coffee." It's not necessary to use the pronoun. "Tengo el café." is adequate.
Scientific notation lets us express a large or a small number without having to write a lot of zeros before or after it. Many constants in physics, for example, are too cumbersome to write without scientific notation. It is easy to make mistakes (in the number of 0s) and you would not be able to enter them into your calculator. For example: Avogadro's constant: 6.022*1023 Planck's constant: 6.626*10-34 Joules second etc.
