How to simplify an expression with a negative exponent

svetlana [45]

Answer:

Step-by-step explanation:

An negative exponent seems hard, but it really isn't!

Let's say you have $2^{-3}$

All you do is inverse the expression, or find the reciprocal. When you do this the exponent changes to positive .

$\frac{1}{2^{3} }$

$2^{3}$ simplifies into 8. So, the result is

$\frac{1}{8}$

Hope this helps! Please mark as brainliest, thanks!

If the area of a park is exactly halfway between 2.4 and 2.5 acres what is the area of the park

Paul [167]

Get the distance between two acres.

2.5 - 2.4 = 0.1

Divide the diffence by 2
0.1 / 2 = 0.05 - Halfway between them.

Therefore, 0.05 must be taken from 2.5 acres. it must be added to 2.4 acres to get the exact area of the park.

2.5 - 0.05 = 2.45
2.4 + 0.04 = 2.45 acres

OR

Simply get the average of the two to get the area since it is exactly halfway between the two acres of land.

2.5 + 2.4 = 2.9 / 2 = 2.45 acres
