You can put this solution on YOUR website! (4r^7)^4
Hello,
Let's expand this out and it'll make sense then.
We could write it as:
(4r^7)(4r^7)(4r^7)(4r^7) (Then let's multiply the 4's first which gives us 256. Now let's find how many r^7's there are. That total 28. So now we can write it as:
256r^28
A faster way is multiply 7 times 4 to give you the power and 4 mutiplied by itself 4 times. In other words (4)(4)(4)(4)= 256
