Video Solution

Solution Steps

00:00 Simplify the following expression
00:03 According to power laws, multiplication with the same base(A) with exponents N,M
00:06 Will equal the same base(A) with exponent (N+M)
00:10 Let's apply this to the problem
00:13 The same base(Y) with exponents(5,1)
00:17 Given that there's multiplication between them, we must add the exponents
00:24 Continue to solve according to the order of operations
00:39 Here is the solution

Step-by-Step Solution

We use the power property to multiply terms with identical bases:

aman=am+n a^m\cdot a^n=a^{m+n} We apply it in the problem:

Y2+Y6Y5Y=Y2+Y6Y5+1=Y2+Y6Y6=Y2 Y^2+Y^6-Y^5\cdot Y=Y^2+Y^6-Y^{5+1}=Y^2+Y^6-Y^6=Y^2 When we apply the previous property to the third expression from the left in the sum, and then simplify the total expression by adding like terms.

Therefore, the correct answer is option D.

Answer

Y2 Y^2
