Question

Evaluate the exponential expression (-n) 4 into (-n) 2, for n=5. answer will be 15625. Give reason.​

Answer 1

(-n)^4×(-n)^2for n =(-5)^4×(-5)^2 by formula if(a)^n×(a)^m=a^m+n =(-5)^4+2 =-5^6 =5×5×5×5×5×5 =15625 ${\:}$

(-n)^4×(-n)^2for n =(-5)^4×(-5)^2 by formula if(a)^n×(a)^m=a^m+n =(-5)^4+2 =-5^6 =5×5×5×5×5×5 =15625

(-n)^4×(-n)^2for n =(-5)^4×(-5)^2 by formula if(a)^n×(a)^m=a^m+n =(-5)^4+2 =-5^6 =5×5×5×5×5×5 =15625

Answer 2

(-n)^4x(-n)^2for n =(-5)^4x(-5)^2 by formula if(a)^nx(a)^m-a^m+n =(-5)^4+2 =-5^6 =5x5x5x5x5x5=15625

(-n)^4x(-n)^2for n =(-5)^4x(-5)^2 by formula if(a)^nx(a)^ma^m+n =(-5)^4+2 =-5^6 = 5x5x5x5x5x5=15625

(-n)^4x(-n)^2for n =(-5)^4x(-5)^2 by formula if(a)^nx(a)^m-a^m+n =(-5)^4+2 =-5^6 = 5x5x5x5x5x5=15625
