Answer: 6400<em>x²</em> · (<em>x - 1)²</em>
The rule says: To multiply exponential expressions which have the same base, add up their exponents.
In our case, the common base is (x-1) and the exponents are:
1, as (x-1) is the same number as (x-1)1
And 1, as (x-1) is the same number as (x-1)1
The product is therefore, (x-1) (1 + 1) = (x-1)²
Answer:
Step-by-step explanation:
Cos(65°) = √(1 + cos(130°)) / 2
0.42=√(1 - 0.64)/2
0.42=√(0.36)/2
0.42²=√0.18²
