Simplify the expression cot^2x - cot^2x cos^2x

andrew-mc [135]

Cot^2x - cot^2x cos^2x
= cot^2x - {(cot^2x)(cos^2x)}
= cot^2x { 1 - cos^2x }
= cot^2x { sin^2x }
= (cos^2x/sin^2x) { sin^2x }
= cos^2x

Please simplify this please it’s due really soon!

iren2701 [21]

Step-by-step explanation:

$\frac{ {13}^{6} \div {13}^{8} \times {13}^{ - 4} }{ {13}^{ - 2} }$

You need to remember the properties of exponents: multiplication adds the exponents, division subtracts the exponents.

If you multiply two powers with the same base, the result will be the base to the sum of the powers.

If you divide two powers with the same base, the result will be the base to the difference of the powers.

In your case you will this:

${13}^{6 - 8 + ( - 4) - ( - 2)}$

That is:

${13}^{ - 4}$

Or:

$\frac{1}{ {13}^{4} }$

Simplify completely 8x^3 ÷ 6x^2 - 4x / -2x

artcher [175]

Answer:

Simplified form is $-(\frac{8x^{3}}{3x-2})$ .

Step-by-step explanation:

The given expression is $8x^{3}\div \frac{6x^{2}-4x}{-2x}$

We can rewrite the given expression as $= 8x^{3}\times (-\frac{2x}{{6x^{2}-4x}})$

Further simplification of the expression gives $=\frac{-16x^{4}}{6x^{2}-4x}$

$=\frac{-16x^{4}}{2x(3x-2)}$

$=-(\frac{8x^{3}}{3x-2})$

So the simplified of the given expression is $=[tex]-(\frac{8x^{3}}{3x-2})$
