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.

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?
100t -16t2 = 0 t4(25-4t) = 0 t = 0 or t = 25/4
The exponent of the base is a step to solve the problems now the exponent of the product will also adjust a step to solve the equation but it contains more cooperative need.
Exponent is repeated multiplication

A fractional exponent is actually finding the nth root of the base. So 80^(3/4) is the 4th root of 80 cubed. This equals 26.750 approximately.

34 = 81 so x is 4
To get something to a negative power, first you must put it on the opposite side of the fraction it would be on currently. Also, when you do this, you switch the negative exponent to a positive exponent. 13^-2 1 = 1 13^2 Solve. 1 169 = 13^-2
You can solve for resistance using the formula ( R = \frac{V^2}{P} ), where R is the resistance, V is the voltage, and P is the power. By rearranging the formula, you can solve for resistance by dividing the square of the voltage by the power.
Solve the exponent first and then subtract it! Ex 5 to the 2 power-20 5 to the 2power = 25-20=5!!
