Question

Hello can u guys help me please

Answer 1

`\displaystyle (1)/(4)`

Explanation:

Given:

`\displaystyle(4^(6) )/(4^(7))`

Expand:

`\displaystyle(4*4*4*4*4*4 )/(4*4*4*4*4*4*4)`

Simplify ones, in this case
`(4)/(4)`:

`\displaystyle (1)/(4)`

If you raise 4 to the power of 6, to the power of 7, and then simplify the fraction, you will get the same result. This method is much quicker when you have numbers with the same bases (here the base is 4) so I used this way.
