Video Solution

Step-by-Step Solution

To solve this problem, we need to simplify the expression b5b2 \frac{b^5}{b^2} using the rules of exponents.

  • Step 1: Identify the rule to apply: For any positive integer exponents m m and n n , the rule aman=amn\frac{a^m}{a^n} = a^{m-n} applies when dividing terms with the same base. In this expression, our base is b b .

  • Step 2: Apply the rule: Substitute the given exponents into the formula: b5b2=b52\frac{b^5}{b^2} = b^{5-2}

  • Step 3: Perform the subtraction: Calculate the exponent 52 5 - 2 : b52=b3b^{5-2} = b^3

Therefore, the solution to the expression b5b2 \frac{b^5}{b^2} is b3 b^3 .

Answer

b3 b^3
