5: Any number (besides zero) to the power of zero is 1.

7: You can make the exponent positive by putting it in the denominator.

12: The (-8) and the 3 each have a negative exponent, so move both of them.

15: Only the factor with the negative exponent will move to the denominator.

21: Change each negative exponent to a positive exponent by changing whether it is in the numerator or the denominator.

26: Add the exponents.

27: This is `p`^{6} × `p`^{6} × `p`^{6} × `p`^{6}.

28: You can multiply the exponents before changing the negative.

30: -7 is (-7)^{1}.

32: Add exponents to multiply, and subtract them to divide.

36: When dividing powers, the exponents are subtracted rather than divided.

39: The numerator and denominator each have a negative exponent, so they both move (that is, the whole fraction gets flipped).

42: -5 and `p`^{3} each need to be raised to the third power.

59: 8 is 2^{3}.

70: The √ symbol means the positive square root.

72: Take the square root of the numerator and the square root of the denominator.
