Describe the error Sadie made, and explain how to find the correct answer. (Refer to image)

1. Sadie should note that $54a^7b^3\ge 0$ and if $a\ge 0$ , then $b\ge 0$ .

2. While simplifying Sadie makes some mistakes (it must be $3^2$ instead of $3^3$ and she missed the sign of absolute value for b). The right way to find the correct answer is:

$\sqrt{54a^7b^3}=\sqrt{3^2\cdot 6\cdot a^2\cdot a^5\cdot b^2\cdot b} =3\cdot a\cdot |b| \sqrt{6\cdot a^5\cdot b}=3ab\sqrt{6a^5b}$ .

3. The simpliest expression is $3ab\sqrt{6a^5b} =3ab\sqrt{6\cdot a^2\cdot a^2\cdot a\cdot b} =3a^3b\sqrt{6ab}$ .
