Step-by-step explanation:
Using the addition identity for sine
sin(x + y) = sinxcosy - cosxsiny
Consider the left side
cos²(45 - A) - sin²(45 - A)
cos²(45 - A) = 1 - sin²(45 - A), thus
1 - sin²(45 - A) - sin²(45 - A)
= 1 - 2sin²(45 - A) ← expand sin(45 - A)
= 1 - 2(sin45cosA - cos45sinA)²
= 1 - 2(cosA - sinA)²
= 1 - 2(cos²A - sinAcosA + sin²A)
= 1 - cos²A + 2sinAcosA - sin²A
= sin²A + 2sinAcosA - sin²A
= 2sinAcosA
= sin2A = right side ⇒ verified

Answer:
Step-by-step explanation:
1. To solve the exercise shown in the problem, you must remember that the exponent 5 indicates the number of times is used as a factor. Therefore, it is used as a factor five times.
2. Therefore, keeping the information above on mind, you have that you can write the expanded form of as following:
