Note that the 5 is the only one that makes a real difference when you add since everything else is just 0.

16^(1/2) is equivalent to the square root of 16 which is 4.

4*4 = 16; 16^(1/2) is the same as $${\sqrt{{\mathtt{16}}}}$$ = 4.

If it were 16^(1/3), then we would have to take the cube root and not the square root.

(8.76 x 109)(6.52 x 10-3)/13.27 x 105

Enter as: [(8.76*10^9)(6.52*10^-3)]/(13.27 x 10^5) = 43.040844009042954.

(2.4 x 10^-9) (4.0 x 10^23) 

= (2.4*10^-9)*(4.0* 10^23)

= 960000000000000

= $$\mathbf{9.6*10^{14}}.$$

Yes, Please Excuse My Dear Aunt Sally.

Question #2 should be positive as Ninja stated: Absolute values make everything inside them positive.

1. |-4| --> taking abs. value means you obtain the positive part --> 4.

2. $$|\frac{3}{2}|$$ = $$\mathbf{\frac{3}{2}}$$.

3. -|1.7| = -(1.7) = -1.7.

5*2*(7+3)+7*0*(5-11)-23-(18*0)

Remember: pemdas [parentheses, exponents, multiplication, division, addition, & subtraction]

We must first evaluate the parentheses -->

5*2*(10)+7*0*(-6)-23-(0)

Next, we must perform multiplication -->

10*10+7*0-23 --> 100+7*0-23 --> 100 + 0 - 23 -->

Note that we had to do multiplication first so it is not 107*0-23.

Finally, we can just add and subtract to obtain our final answer -->

100 + 0 - 23 = 100 - 23 = 77.

It is just a specific model of Xerox [a company that makes photocopiers/printers/etc.]

Like: Lenovo G655 or Dell XPS or HP Deskjet 3910.

Please provide the question.
