1。 The absolute value of -4 is equal to 4, the root number 9 is equal to 3, the square of 3 is equal to one ninth, and the power of 0 of any number is equal to 1.

So it can be simplified to 4-3+1/9-1=1/9, which is one ninth.

2。 The root number 8 is equal to twice the root number 2, the odd power of-1 is equal to-1, and the absolute value of-root number 2 is equal to root number 2.

So it can be simplified, 2 times the root number 2- 1- root number 2= root number 2- 1.
