WebbDavid Severin. 2 years ago. The rule for dividing same bases is x^a/x^b=x^ (a-b), so with dividing same bases you subtract the exponents. In the case of the 12s, you subtract -7- (-5), so two negatives in a row create a positive answer which is where the +5 comes from. In the x case, the exponent is positive, so applying the rule gives x^ (-20-5). WebbSOLUTION: Rewrite the expression without using a negative exponent. 4z^-4 Simplify your answer as much as possible. is this right? (1/4z^4) Rewrite the expression without using …

WebbA negative exponent just means that the base is on the wrong side of the fraction line, so you need to flip the base to the other side. For instance, " x−2 " (pronounced as "ecks to the minus two") just means " x2, but underneath, as in \frac {1} {x^2} x21 ". WebbQuestion: Simplify the expression. Write the answer without using negative exponents. Assume that the variable is restricted to those numbers for which the expression is defined.

WebbDividing! A negative exponent means how many times to divide by the number. Example: 8-1 = 1 ÷ 8 = 1/8 = 0.125 Or many divides: Example: 5-3 = 1 ÷ 5 ÷ 5 ÷ 5 = 0.008 But that can be done an easier way: 5-3 could also be calculated like: 1 ÷ (5 × 5 × 5) = 1/53 = 1/125 = 0.008 That last example showed an easier way to handle negative exponents: WebbNote that rational exponents are subject to all of the same rules as other exponents when they appear in algebraic expressions. Both simplification methods gave the same result, a 2.Depending on the context of the problem, it may be easier to use one method or the other, but for now, you’ll note that you were able to simplify this expression more quickly using … WebbLearn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more.
