In the lcm of 3a^2b^4c^5 and 7a4bc^2, what is the exponent on the b?

a)1
b)4
c)5
d)6

sorry that i suck at math! ~ -katie

is a^2bc^2

so the exponent of b is 1

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.
