A negative power just means to invert it. Let's say we had x^(-2) - it is the same thing as 1/(x^2).
A negative power is equivalent to a reciprocal.So, 4-2= 1/42= 1/16
5 to the power of 2
3 to the power of 1 is 3. 3 to the power of minus 2 is equal to 1 over 3 to the power of 2. 3 to the power of 2 is 9. 3 to the power of 1 times 3 to the power of minus 2 is the same as... 3 divided by 3 to the power of 2. So that gives us 3 divided by 9 which is the same as 1/3.

49 - 8 - 6 = 35
5 to the power of 2
49 - 8 - 6 = 35
3 to the power of 1 is 3. 3 to the power of minus 2 is equal to 1 over 3 to the power of 2. 3 to the power of 2 is 9. 3 to the power of 1 times 3 to the power of minus 2 is the same as... 3 divided by 3 to the power of 2. So that gives us 3 divided by 9 which is the same as 1/3.
6 divide 2 multiplied by 1 to the third power minus 2 is 1.
