Question

I need help with this on I don't really get it.

Answer 1

So, we know that exponentiation is really just repeated multiplication. That means for this problem, we can really just write this as:

`(7*7*7*7*7*7)/(7*7*7*7)`

We see that both the numerator and the denominator share 4 7s, which means we can cancel them out:

`7*7*(7*7*7*7)/(7*7*7*7)=7*7=49`

Answer 2

we have give given that
`(7^6)/(7^4)`.

we need to simplify this.

we know that base and exponent rule.

`(a^n)/(a^p) =a^(n-p)`.

`(7^6)/(7^4) =7^(6-4)=7^2`.

so
`7^2=49 .`
