Question

Which is the correct term when simplifying 5√5×4√3?

A.) 15
B.) 2√2
C.) 20√15
D.) √15

Answer 1

C. 20√15 is the correct answer.  First you had to multiply by the numbers, and it gave us, $5*4=20$, and $20\sqrt{5} \sqrt{3}$. Then you had to used apply radical rule, and it gave us, $\sqrt{5} \sqrt{3}=\sqrt{5*3}$, and $=20\sqrt{5*3}$. And finally multiply by the numbers, and it gave us the answer is $5*3=15$, and  20√ 15 is the final answer. You can also round up to the nearest hundredths is 77.45 to 77.50. Hope this helps!
