The notation -1.7E-4 represents -1.7 times 10 raised to the power of -4. This can be expressed as:
-1.7 × 10^-4
Now, let's evaluate the other options:
- 1.7 × 10^-4 - This is positive, so it does not represent the same value as -1.7E-4.
- -1,700 - This is not equivalent; it is much larger in magnitude.
- 0.00017 - This is positive, so it does not represent the same value.
- -0.00017 - This is equivalent because -0.00017 is the decimal representation of -1.7E-4.
- -1.7 × 10^-4 - This is exactly the same as -1.7E-4.
So, the equivalent numbers are:
- -0.00017
- -1.7 × 10^-4
