Answer:

2^14

Step-by-step explanation:

Odd powers of negative value is a negative value

Even powers of positive value is positive

(-2)^7 = - 2^7

( -2) ^3 = - 2^3

(-2)^4 = 2^4

multiply all these

-2^7×-2^3×2^4 = 2^7×2^3×2^4

since minus × minus = plus

from law of exponents 2^7×2^3×2^4 = 2^7+3+4

2^14

Answer 2

Answer:

16384
