When you have a negative exponent on, say, 4, it will be written 4^-2 You basically take the reciprocal of it and change the exponent to a positive one. 4^-2 would be 1/4^2
Squared implies exponent = 2.
It is: 21a exponent 6
4
5x^2(x^2 + 5)
4 is the base, 2 is the exponent.
An exponent is 1; 16 = 16^1

2^2
A base number is the value to the power of the exponent. For example, in 2^4, 2 is the base number and 4 is the exponent.
(4x^-4)^-2 = ?
4 = 2 * 2 = 22
An expression with a negative exponent is equivalent to the positive exponent of its reciprocal. Thus, 3-4 = 1/34 or, equivalently, (1/3)4 or (3/4)-2 = (4/3)2
