Two numbers are written in scientific notation. the number with a positive exponent is divided by the number with a negative exponent. describe the result. explain your answer

Explanation:

When the division is performed, the denominator exponent is subtracted from the numerator exponent. Subtracting a negative value from the numerator exponent will increase its value.

Example:

_____

Another way to think about it is this. An exponent in the denominator is the same as the opposite of that exponent in the numerator. Multiplying exponential numbers with the same base adds their exponents.

Example:

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

1. perpendicular

2. parallel

3. perpendicular
