You know
Squaring both sides gives
Then raising both sides to any integer power gives
That is, any power of where the power is a multiple of 4 will always be equal to 1.

But perhaps you mean to write 20+1 as the exponent, in which case
Answer:
The number is -4.
Step-by-step explanation:
Let the number be n.
Given:
Max adds 7 to a number.
hence it is given as n+7
Multiply's the sum by -4 the result is 3 times the same number.
Hence the equation can be written as;
Now Solving the above equation to find value of n we get;
The value of n is -4.
Now when we add 7 to number -4 we get answer as 3.
And when the sum is multiplied by -4 we get answer -12.
Also 3 times of number is equal to 3 multiplied by -4 we get answer as -12.
Hence when the sum is multiplied by -4 it is equal to 3 times of same number.
Hence from above we can say that the number is -4.
