Answer:
2nd answer option : 6^(13/4)
Explanation:
what are we doing, when 2 equal base terms with exponents are multiplied ? we add the exponents !
this is like 3⁴×3³ = 3⁷
because
3×3×3×3 × 3×3×3 = 3×3×3×3×3×3×3 = 3⁷
it is that simple.
and that concept is also valid for any kind of number as exponent. even for fractions and so on.
so,
6^3 × 6^(1/4) = 6^(3 + 1/4) = 6^(12/4 + 1/4) = 6^(13/4)
