Question

Multiply or divide as indicated. 20b²c³/4bc

Answer 1

5bc²

Explanation:

`(20b^2c^3)/(4bc)=\left((20)/(4)\right)\left((b^2)/(b)\right)\left((c^3)/(c)\right)\qquad\text{use}\ (a^n)/(a^m)=a^(n-m)\ \text{and}\ a=a^1\\\\=5b^(2-1)c^(3-1)=5bc^2`

Answer 2

We can separate this into three parts.

20/4 = 5
B^2/b= b
C^3/c = c^2

Therefore, the answer is 5bc^2
