- To simplify, expand the multiplication and remember how to multiply fractions: {left (frac {1} {2}right)}^ {3}=frac {1} {2}cdot {frac {1} {2}}cdot {frac {1} {2}}=frac {1} {8} (21)3 = 21 ⋅ 21 ⋅ 21 = 81 3) 2x^ {3} 2x3 The exponent on this term is 3, and the base is x, the 2 is not getting the exponent because there are no parentheses that tell us it is.

- Zero Exponent Property. [latex]{b^0} = 1[/latex] Any nonzero number raised to zero power is equal to 1. Examples: Simplify the exponential expression [latex]{5^0}[/latex].
- Negative Exponent Property. Any nonzero number raised to a negative exponent is not in standard form. We will need to do some rearranging. Move the base with a negative exponent to the opposite side of the fraction, then make the exponent positive.
- Product Property of Exponent. When multiplying exponential expressions with the same base where the base is a nonzero real number, copy the common base then add their exponents.
- Quotient Property of Exponent. When dividing exponential expressions with the same base where the base is a nonzero real number, copy the common base then subtract the top exponent by the bottom exponent.
Let’s simplify [latex]\left(5^{2}\right)^{4}[/latex]. In this case, the base is [latex]5^2[/latex] and the exponent is 4, so you multiply [latex]5^{2}[/latex] four times: [latex]\left(5^{2}\right)^{4}=5^{2}\cdot5^{2}\cdot5^{2}\cdot5^{2}=5^{8}[/latex] (using the Product Rule—add the exponents). [latex]\left(5^{2}\right)^{4}[/latex] is a ...

Writing all the letters down is the key to understanding the Laws So, when in doubt, just remember to write down all the letters (as many as the exponent tells you to) and see if you can make sense of it.
The "Laws of Exponents" (also called "Rules of Exponents") come from three ideas: If you understand those, then you understand exponents! And all the laws below are based on those ideas.
The first three laws above (x1 = x, x0 = 1 and x-1 = 1/x) are just part of the natural sequence of exponents. Have a look at this: Look at that table for a while ... notice that positive, zero or negative exponents are really part of the same pattern, i.e. 5 times larger (or 5 times smaller) depending on whether the exponent gets larger (or smaller...
With xmxn, how many times do we end up multiplying "x"? Answer: first "m" times, then by another"n" times, for a total of "m+n" times.
Like the previous example, how many times do we end up multiplying "x"? Answer: "m" times, then reduce thatby "n" times (because we are dividing), for a total of "m-n" times. (Remember that x/x = 1, so every time you see an x"above the line" and one "below the line" you can cancel them out.) This law can also show you why x0=1:
OK, this one is a little more complicated! I suggest you read Fractional Exponentsfirst, so this makes more sense. Anyway, the important idea is that: x1/n = The n-th Root of x And so a fractional exponent like 43/2 is really saying to do a cube (3) and a square root(1/2), in any order. Just remember from fractions that m/n = m × (1/n): The order d...
If you find it hard to remember all these rules, then remember this: you can work them out when you understand the three ideasnear the top of this page: 1. The exponent sayshow many timesto use the number in a multiplication 2. A negative exponent meansdivide 3. A fractional exponent like 1/n means totake the nth root: x(1n) = n√x
The exponent of a number says how many times to use the number in a multiplication. In words: 8 2 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared". Exponents make it easier to write and use many multiplications. Example: 96 is easier to write and read than 9 × 9 × 9 × 9 × 9 × 9.
