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} .
