Question

Which expressions are equivalent to 2^5 over 6^5pick two a) 1/3b) 3^-5c) (-4)^5d) 2^5 * 6^-5

Answer 1

`(2^5)/(6^5)`
`(2*2*2*2*2)/(6*6*6*6*6)\text{ =}(1)/(3*3*3*3*3)=\text{ }(1)/(3^5)`
`(1)/(3^5)=3^(-5)`

So the correct answer is the option (b).

`(2^5)/(6^5)=2^5*6^(-5)`

so the option (d) is also correct.
