What is the difference between -(4) to the power of 7, (-4) to the power of 7, -4 to the power of 7, i'm lost and my teacher won't

For -(4)^7
the - is not affected by the power of 7

For (-4)to the power of7 is the same as -4 to the power of 7

It is because 7 is an odd number,the - will not change .Therefore
(-4)^7= -(4)^7

But keep in mind that if the power is an even number , the - will change to + when the situation is (-4)
For example,(-4)^4=(4)^4
