Change the exponential expression to an equivalent expression. It should involve an a logarithm.
6.5=a^3
This is what I have. can you help me out.
Ina[1/3]In6.5

This is hardly calculus.
take log of both sides
ln(6.5)=3lna
1/3 ln(6.5)=ln a
when one asks for an equivalent expression, one can get many, many solutions.
