A negative exponent of a number is the same as the reciprocal of that same number to the equivalent positive exponent.
EXAMPLE : 2-3 = 1/23
When multiplying powers of the same base the rule is, addthe exponents.
So, if the initial exponent is negative then the number has to be multiplied by a power of that number with an equivalent positive exponent greater than the negative exponent.
EXAMPLE : 2-3 x 25 = 2(-3+5) = 22 (As 5 > l3l then the resultant exponent is positive)

by doing reciprocal
What the difference between negative rate of change and positive rate of change?
A quantity with a negative rate of change becomes smaller as time goes on. A quantity with a positive rate of change becomes larger as time goes on.
If you change the number of electrons you get a positive negative or neautraul?
That depends on how you change the number of electrons.
Is there a relationship between the sign of the slope of a line and the angle the line makes with the x-axis?
Yes, there a relationship between the sign (positive or negative) of the slope of a line and the angle the line makes with the x-axisWhen a line slopes up from left to right, it has a positive slope. This means that a positive change in y is associated with a positive change in x. The steeper the slope the greater the rate of change in y in relation to the change in x.When a line slopes down from left to right, it has a negative slope. This means that a negative change in y is associated with a positive change in x.
