\(\frac{6^4 - 6^3}{5} =\)
Taking \(6^3\) common, we get
\(6^3(\frac{6 - 1}{5})\)
\(6^3(\frac{5}{5})\)
\(6^3\) ... 'B' is the winner

\(\frac{6^4 - 6^3}{5}\)
= \(\frac{6^3 ( 6 - 1)}{5}\)
= \(\frac{6^3*5}{5}\)
= \(6^3\), Answer must be (B)

Solution
Given
In this question, we are given that
- • An expression: \(\frac{{6^4 – 6^3}}{5}\)
To find
We need to determine
• The simplified value of the given expression
Approach and Working out
Numerator of the expression = \(6^4 – 6^3 = 6^3 (6 – 1) = 5 * 6^3\)
• Hence, the value of the expression = \(\frac{{5 * 6^3}}{5} = 6^3\)
Thus, option B is the correct answer.
Correct Answer: Option B
