00:00 Identify the correct solution
00:03 According to the laws of exponents, the multiplication of powers with an equal base (A)
00:07 equals the same base raised to the sum of the exponents (N+M)
00:11 Let's apply the formula and check if this solution is correct
00:16 Upon solving the problem we can observe that the powers are not equal, therefore it's incorrect
00:23 Let's solve the remaining options using the same method
00:30 We can see that this solution is also incorrect
00:38 Let's continue to the last option
00:43 This one also doesn't fit, therefore none of the expressions are correct
00:47 This is the solution
