An exponent means "this many times." So, 4 cubed (to the power of 3; a 3 exponent.) is 4 NOT times 3, but 3 TIMES. So it is 4x4x4(=64). Or, 5 to the power of 5 is 5 times itself 5 times, so, 5x5x5x5x5(=3,125). 3 to the power of 9 is 3 times itself 9 times. Basically, the exponent tells how many times you multiply the number by itself. Does that help?

How do you solve when you have a negative exponent?
A negative exponent is the same as 1/(the positive exponent). For example, 2^3 is (2*2*2) = 8. 2^(-3) is 1/(2*2*2) = 1/8. So, just calculate the positive exponent version, and put it under 1.
How do you solve algebraic expressions with missing exponents?
You cannot because an exponent cannot be solved: only an equation or inequality can be solved. In any case, the answer will depend on the nature of the equation and which exponent is missing. Without that information there cannot be any sensible answer.
How do you solve 16y exponent 3 20y exponent 4?
16y3 / 20y4 = 16/20 * y3/y4 = 4/5 * y3-4 = 4/5 * y-1 or 4/5y
How do you solve an exponent if it's by the power of zero?
Any exponent to the power of zero is simply 1, with the exception of zero itself! Zero to the power of zero has no definitive answer, though it may sometimes be taken as equal to one.
