What is the simplified form of 5 square root x^4 • 5 square root x^4

laiz [17]

Answer: C

Step-by-step explanation:

You can write each term into a fraction.

$\sqrt[5]{x^4}$ becomes $x^4^/^5$

When you multiply 2 terms with the same base, you add the exponents.

$x^4^/^5*x^4^/^5=x^4^/^5^+^4^/^5=x^8^/^5$

$x^8^/^5$ is also the same as $x\sqrt[5]{x^3}$

You get this because $\sqrt[5]{x^8} =\sqrt[5]{x*x*x*x*x*x*x*x}$ . When you pull out 5 os x, you are left with x³ on the inside.

Answer:

$-\cos nw_0t$

Step-by-step explanation:

We can use the double angle identity for sine.

$\sin (A+B)=\sin A \cos B+\sin B\cos A$

The given expresion is

$\sin (nw_0t-90)$

We apply the identity to get:

$\sin (nw_0t-90)=\sin nw_0t \cos 90-\cos nw_0t \sin 90$

We simplify to obtain;

$\sin (nw_0t-90)=\sin nw_0t (0)-\cos nw_0t (1)$

This simplifies to:

$\sin (nw_0t-90)=-\cos nw_0t$ The correct answer is D
