how to simplify this​

Answer 1

Answer:

mark me brainliest

Step-by-step explanation:

if bases are same then powers are equal

now in multiplication of exponents the powers get added

so

-7/2 + -1/2

since they have same denominators

they can be added easily.

So,

-7 + -1/2

-7 -1/2

-8/2

-8/2 = -4
