00:00 Simplify the following problem
00:03 According to the exponent laws, the multiplication of exponents with equal bases (A)
00:09 equals the same base raised to the sum of the exponents (N+M)
00:13 We'll apply this formula to our exercise
00:19 We'll maintain the base and add the exponents together
00:33 According to the exponent laws, any number with a negative exponent (-N)
00:36 equals its reciprocal raised to the opposite exponent (N)
00:39 We'll apply this formula to our exercise
00:42 We'll convert to the reciprocal and raise to the opposite exponent
00:48 This is the solution

Step-by-step solution

Let's solve the problem step-by-step:

  • Step 1: Identify the base and exponents involved.
  • Step 2: Apply the exponent multiplication rule to simplify.
  • Step 3: Further simplify the expression if necessary.

Now, we will work through each step:

Step 1: The problem gives us the expression 65×62 6^{-5} \times 6^2 . We have a common base, which is 6.

Step 2: Using the rule for multiplying exponents with the same base, we add the exponents. Thus, 65×62=65+2=63 6^{-5} \times 6^2 = 6^{-5+2} = 6^{-3} .

Step 3: Simplifying further, since a negative exponent means the reciprocal, we have:
63=163 6^{-3} = \frac{1}{6^3} .

Therefore, the solution to the problem is: 163 \frac{1}{6^3} .
