Question 255637
36. Simplify the sums and differences. Give exact answers. 
(3sqrt2)(-4sqrt10)
---
= -12 sqrt(20)
= -12sqrt(4)*sqrt(5)
= -12*2*sqrt(5)
= -24sqrt(5)
=================
 
88. Simplify each expression. 
sqrt(2t^5) *sqrt(10t^4)
---
= sqrt(20t^9)
---
= sqrt(4t^8)*sqrt(5t)
---
= 2t^4*sqrt(5t)
