Video Solution

Solution Steps

00:00 Simplify the following problem
00:03 According to the laws of exponents, the multiplication of exponents with an equal base (A)
00:06 equals the same base raised to the sum of the exponents (N+M)
00:09 We'll apply this formula to our exercise
00:12 Note that we are adding a negative factor
00:18 A positive x A negative is always negative, therefore we subtract as follows
00:21 This is the solution

Step-by-Step Solution

To solve the problem of simplifying 26×23 2^6 \times 2^{-3} , we follow these steps:

  • Identify the problem involves multiplying powers with the same base, 2 2 .

  • Use the formula am×an=am+n a^m \times a^n = a^{m+n} to combine the exponents.

  • Add the exponents: 6+(3) 6 + (-3) .

Applying the exponent rule, we calculate:

Step 1: Given expression is 26×23 2^6 \times 2^{-3} .

Step 2: According to the property of exponents, add the exponents: 6+(3) 6 + (-3) .

Step 3: Simplify the exponent: 63=3 6 - 3 = 3 .

Thus, 263 2^{6-3} .

Answer

263 2^{6-3}
