- \(3^2 ~; ~9\)
- \(5^3~ ; ~ 125\)
- \(2^5~ ;~ 32\)
- \(2^2\cdot3^3~ ; ~108\)
- \(\bigg(\dfrac12\bigg)^3=\dfrac18\)
- \(9x^4\)
- The perimeter is \(3+3+3+3\) or \(4\cdot3=12\). The area is \(3\cdot3\) or \(3^2=9\). For perimeter you add four “3’s” or multiply 3 by 4, and for area, you multiply “3” by itself or square 3.
- \(5\cdot 2x\) or \(10x\) ; \((2x)^5\) or \(32x^5\)
- \((-2)^3=(-2)\cdot (-2)\cdot (-2)=-8\) and \(3(-2)=(-2)+(-2)+(-2)=-6\)
