Video Solution

Solution Steps

00:00 Simplify the following problem
00:03 According to the laws of exponents, a number raised to the power of (-N)
00:06 equals the reciprocal number raised to the opposite power (N)
00:09 We will apply this formula to our exercise
00:12 We'll convert to the reciprocal number
00:15 and raise to the opposite power (times(-1))
00:18 This is the solution

Step-by-Step Solution

To solve this problem, we'll use the rule of negative exponents:

  • Step 1: Identify that the given expression is 132\frac{1}{3^2}.
  • Step 2: Recognize that 132\frac{1}{3^2} can be rewritten using the negative exponent rule.
  • Step 3: Apply the formula 1an=an\frac{1}{a^n} = a^{-n} to the expression 132\frac{1}{3^2}.

Now, let's work through these steps:

Step 1: We have 132\frac{1}{3^2} where 3 is the base and 2 is the exponent.

Step 2: Using the formula, convert the denominator 323^2 to 323^{-2}.

Step 3: Thus, 132=32\frac{1}{3^2} = 3^{-2}.

Therefore, the solution to the problem is 323^{-2}.

Answer

32 3^{-2}
