Answer:
25
Step-by-step explanation:
Expression: <em>(2⁸ ⋅ 5⁻⁵ ⋅ 19⁰)⁻² ⋅ (5⁻²/2³)⁴ ⋅ 2²⁸</em>
Inner-most powers: 2⁻¹⁶ • 5¹⁰ • 1 • 5⁻⁸/2¹² • 2²⁸
Combine like terms: 2¹² • 5²/2¹²
Cancel out: 5²
Solve: 25
Answer:

Step-by-step explanation:
The formula of a volume of a rectangular box:

<em>l</em><em> - lenght</em>
<em>w</em><em> - width</em>
<em>h</em><em> - height</em>

Therefore the dinemsions of thisp prism are:

<span>Round off the answer correctly.. . 8.7 g + 15.43 g + 19 g = 43.13 g .
a. 43.130 g.
b. 43.1 g.
c. 43 g.
d. None of the above..
From the above given answers , most appropriate answer is "43.1" g. as according to the rounding rules, if the last number of digit is smaller than 5, then </span> <span>we leave the digit we want to round to alone.</span>
(g/f)(x)= g(x)/f(x) =
= (x² - 6) /(3x +1)
3x+1≠0
3x≠-1
x≠ - 1/3
(g/f)(x)= (x² - 6) /(3x +1), when x≠ - 1/3
Answer: A.
