\sqrt{16}  \sqrt{ {a}^{2} }

4 \sqrt{ {a}^{2} }

4) Simplify.

4a

What is the GCF of 44j5k4 and 121j2k6?<br><br> 4j3k2<br> 4j2k4<br> 11j3k2<br> 11j2k4
egoroff_w [7]

Answer:

D) 11j2k4

Step-by-step explanation:

Simply find the prime factors of each term!

44 j5 k4

121 j2 k6

11 goes into 44 and 121. So, we can use 11!

2 works for j5 and j2, because of 10, so you would input j2.

4 works for both k4 and 46 because of 24, so k4.

11 j2 k4

Hope this helps! :)
