A negative exponent is the same as the reciprocal of the number with a positive exponent.Thus 2^(-4) is the reciprocal of 2^4.
Now 2^4 = 16 and the reciprocal of 16 is 1/16 so 2^-4 = 1/(2^4) = 1/16 = 0.0625
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
negative 4 with negative 3 as an exponent
Not always. (-4)-2 = 1/(-4)2 = 1/16 which is positive. (-4)-3 = 1/(-4)3 = 1/(-64) which is negative.
A result is positive in a negative power when the base is a negative number and the exponent is an even integer. For example, ((-2)^{-2} = \frac{1}{(-2)^2} = \frac{1}{4}), which is positive. In contrast, if the exponent is an odd integer, the result will be negative. Thus, the sign of the result depends on the base and the parity of the exponent.
A number with a negative exponent should be treated as the reciprocal of that same number with the analogous positive exponent. For example, 42 = 16, but 4-2 = 1/42 = 1/16.

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
negative 4 with negative 3 as an exponent
Not always. (-4)-2 = 1/(-4)2 = 1/16 which is positive. (-4)-3 = 1/(-4)3 = 1/(-64) which is negative.
-2^2=-4 This is because -2^2 is the same as the expression -(2*2). When a negative number has an exponent greater than 2 it is negative.
A number with a negative exponent should be treated as the reciprocal of that same number with the analogous positive exponent. For example, 42 = 16, but 4-2 = 1/42 = 1/16.
if its like this: (these are exponents by the way) -8 - (-4) = 4 * * * * * Unfortunately, that is wrong! -8 - (-4) = -8 + 4 = -4 not +4.
A negative exponent is 1 over the base to the power of the absolute value of the exponent. For example 2 to the power of -1 is 1/2, 2 to the power of -2 is 1/4, or (1/2) squared, and 2 to the power of -3 is 1/8, or (1/2) cubed.
The result is a negative number which may or may not have an exponent. For example, -2*102 times 4 = -8*102 -2*102 times 0.04 = -8
When you have a number raised to a negative exponent, you move to the left rather than the right in decimal places. E.g. 103 = 1000 10-3 = 0.001 More specifically, when you have a negative exponent, you are taking the reciprocal of what the positive exponent would give. 24 = 16, but 2-4=(1/16) ■
A negative exponent is the reciprocal of the corresponding positive exponent. 102 = 100 10-2 = 1/100
Example: (4x)-2 The answer to this would be 1/ 16x2. Multiply it out as if the negative exponent was not there ((4x)2), then that will be the denominator of the fraction. The numerator is one.
