EXPS 1 | Lesson 1 | Practice (Mixed Review) Solutions

1.   \(7^2=49\) and \(3^4=81\); thus, \(3^4>7^2\)

2.   \((-3)^3=-27\) and \(3^{-3}=\dfrac{1}{3^3}=\dfrac{1}{27}\); thus, \(3^{-3}>(-3)^3\)

3.   \(3^{-2}=\dfrac{1}{3^2}=\dfrac{1}{9}\); thus, \(\dfrac19>-6\)

4.    \(5^0=1=(-2)^0\); thus, they are equal

5.   true

6.   false; they both \(=9\)

7.   false; \(25\) is larger than \(1\)

8.   false;  \((x^2y^2)^0=1\)
