Let as described in the problem statement. Plugging in
and
gives us the equations
and
Since
are nonzero, we divide the second equation by the first to get
which means that
after taking the cube root. Plugging this value for
into the first equation, we now have
Solving gives
and our desired exponential equation is
Answer:
not equivalent
Step-by-step explanation:
Given
=
If the ratios are equivalent then ib cross- multiplying the 2 sides should be equal, that is
6 × 9 should equal 7 × 7
However, 54 ≠ 49
Thus the ratios are not equivalent
