Answer 2

Answer:

The value of (i)=16 , (ii) = 17/4 , (iii) = 61/4 , (iv) = 22

Step-by-step explanation:

(i) m= -2 , n= 2

 $m^{2}$ + $n^{2}$ - 2nm

$(-2)^{2}$ + $(2)^{2}$ - 2×(-2)×2

 4+4+8

 16

(ii) mⁿ + $n^{m}$

$(-2)^{2}$ + $2^{-2}$

= 4+ 1/4

= 17/4

(iii) 6$m^{-3}$ + 4$n^{2}$

   = 6×$(-2)^{-3}$ + 4×$2^{2}$

   = 6/(-8) + 4×4

   = -3/4 +16

   = $\frac{-3+64}{4}$

   = 61/4

(iv) 2$n^{3}$ - 3m

   =2×$2^{3}$ -3×(-2)

   =2×8+6

   = 22
