Simplify: 4^ sqrt 400/ 4^ sqrt 5 <br> SHOW WORK
USPshnik [31]

Given  

The equation is in the form

=\frac{4^{\sqrt{400}}}{4^{\sqrt{5}}}

Simplify the above equation

To proof

As given in the question the equation is written in the form

=\frac{4^{\sqrt{400}}}{4^{\sqrt{5}}}

By using the exponent property

when you divide powers with the same base you just have to subtract the exponents. i.e

\frac{y^{a}}{y^{b}} = y^{a-b}

y is not equal to zero.

Now apply this property to the above equation

=4^{\sqrt{400}- \sqrt{5}}

As

\sqrt{400} = 20

now put this in the above equation

we get

=4^{20- \sqrt{5}}

Hence proved

Two forces act on an object. The first Force has a magnitude of 400 Newtons and acts at an angle of 30 degrees as measured from
Sedaia [141]

ANSWER

Option D is correct

EXPLANATION

We resolve the forces into component forms.

F_1 = 400 \cos(30) i + 400 \sin(30) j

F_1 = 200  \sqrt{3} i +200j

Also the second is resolved to obtain,

F_2= 280 \cos(135) i + 280 \sin(135) j.

F_2=  - 140 \sqrt{2} i + 140  \sqrt{2}  j

To find the resultant vector, V, We add the corresponding components of the two forces to get:

V=F_1+F_2

\implies \: V = (200  \sqrt{3} - 140 \sqrt{2} )i + (200 + 140 \sqrt{2})j

The correct answer is D.
