Question

Not a timed or graded assignment. Please use factor tree. Quick answer = amazing review :)

Answer 1

72 can be written as 8 x 9

72 = 8 x 9 = 2^2 x 2 x 3^2

Thus, the expression can be rewritten as

`\begin{gathered} 3\sqrt[]{72}\text{ = 3}\sqrt[]{2^2*2*3^2}\text{ = 3 }*3*2\sqrt[]{2} \\ =\text{ }3\text{ }*6\sqrt[]{2} \end{gathered}`

The factor tree is shown below
