Answer 1

Hello!

Scientific notation is a number 1-10 multiplied by
`10^(x)`. Therefore we need to multiply our number by
`10^(5)` to get a digit 1-10. Since we multiplied up, our final answer will be ten to a negative exponent to show that the number is smaller than a digit 1-10.

7.52·
`10^(-5)`.

The correct answer is E

I hope this helps!
