we have given that [tex] (-5)*(-5)*(-5)*(-5)=(-5)^4 [/tex]
we need to check for equality .
we know that (-5)*(-5)*(-5)*(-5)=(5)^4 as we know that bases are same power are added up.
if we have (-5)^4 we even power here so if we multiplied we wont negative in our answer .
[tex] (-5)*(-5)*(-5)*(-5)=(-5)^4 [/tex] is equivalent.
both will have same value.
