8 0

Prime factorization of 1728 is 2 × 2 × 2 × 2 × 2 × 2 × 3 × 3 × 3
Simplifying the above expression: 26 × 33
Simplifying further: 123
Therefore, the cube root of 1728 by prime factorization is (2 × 2 × 2 × 2 × 2 × 2 × 3 × 3 × 3)1/3 = 12

Prove each of these identities.

Stella [2.4K]

Answer:

Identity (a) can be re-written as

$sec x\ cosec x - cot x = tan x$

which we already proven in another question, while for idenity (b)

$(A)\frac 1 {sin x} -sin x = cos x \frac{cos x}{sin x}\\\\(B)\frac {1-sin^2x}{sin x} = \frac {cos^2x} {sin x} \\\\(C) \frac {cos^2x}{sin x} =\frac {cos^2x} {sin x}$

step A is simply expressing each function in terms of sine and cosine.

step B is adding the terms on the LHS while multiplying the one on RHS.

step C is replacing the term on the numerator with the equivalent from the pithagorean identity $cos^2x + sin^2x = 1$

Which mathematical law or property is used to rewrite the following expression?

ra1l [238]

<h3>Answer: Commutative Property Of Addition</h3>

Explanation:

This property is where we have A+B = B+A. In other words, adding two numbers can be done in any order. This can be extended to more than two values also.

So, 4+6 = 6+4 since both sides result in 10.

Overall it leads to 2+(4+6) = 2+(6+4) being a true equation as well. Both sides simplify to 12.
