7n²mp⁴ • 3n³m⁴p-⁴ (that's supposed to be a negative exponent)

When we are multiplying eponents with the same base, we do is writing the sum of both exponents:

SO, in our case:

We have to do this three times and multiply the numbers:

= (any number whose exponent is equal to 0 has a value of 1) =

So now we know that =

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
