Select the answer choice that equals the given expression. 8^-3 x 8^-2 x ^5
Alexus [3.1K]

Answer:

B) 1

Step-by-step explanation:

Given:

8^{-3}\times 8^{-2}\times8^5

We need to solve the given expression.

Now We know that when base of the exponents then the law of indices applied for the same.

Now According to Law of Indices.

x^a\times x^b = x^{a+b}

On Solving the above expression we get;

8^{-3+(-2)+5}\\\\8^{-3-2+5}\\\\8^{-5+5}\\\\8^0\\\\\textrm{Now Again by law of indices;}\\\\a^0 =1\\\\Hence\ 8^0 = 1

Hence The Simplified form of given expression is 1.

Let u=  (-1,3) and w =(2,4) Find the resulting vector of 2u-4w  in component form..
IgorLugansk [536]
Very simple. You just use the vectors as normal numbers, and multiply the coordinates with 2 and 4 like this: 

2*u = 2* (2,4) = (4,8)
4*w = 4* (-1,3) = (-4,12)

(4,8) - (-4,12) = (8,-4)

So the vector has the coordinates (8,-4)
