Question

4. If p=-2,q=-1 and r= 3, find the value of :
(f) p⁴+q⁴‐r⁴​

Answer 1

Answer:

this is your answer

Step-by-step explanation:

P⁴+q⁴-r⁴=(-2)⁴+(-1)⁴-(3⁴)

We know that (ab)^n=a^n×b^n

so,

(-1)⁴(2)⁴+(-1)⁴-(3)⁴

16+1-81. because (-1)^n=1 if n is even

And (-1)^n=-1. if n is odd.

17-81

-64

hope it helps

Answer 2

Answer:

p^4+q^4-r^4

(-2)^4+(-1)^4-(3)^4

16+1-81

-64
