You have to distribute the exponent of 4 to the whole equation.
so step one is to distribute to the 3
3^4= 81
then we have to distribute to the x
x^4
then to the 2
2^4= 16
81 * x^4 * 16
* = multiplication sign
3 *4 12 have
- =
7 *4 28 total
28-12=16
'dz' because d and z are different values.
He would have walked 5 kilometers because 12 goes into 60 5 times
