Answer:
A. x=-15 and x=3
Step-by-step explanation:
|x+6|+8=17
|x+6|=9
-1(x+6)=9 x+6=9
-x-6=9 x=3
-x=15
x=-15
An addition sign between 978 and 842 would make the equation true!
3²×2^4 ×3³×2=
3^5×2^5=
243 × 32 = 7776
The answer would be A. <3 hope this helps!

<h2>Exponent</h2>
Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.
<h3>Simplification</h3>
Simplification is to make something easier to do or understand and to make something less complicated.
Given
is an expression.
<h3>How to make it simple?</h3>
![\rm 2\sqrt{8x^3} * (3\sqrt{10x^4} - x\sqrt{5x^2} )](https://tex.z-dn.net/?f=%5Crm%202%5Csqrt%7B8x%5E3%7D%20%2A%20%283%5Csqrt%7B10x%5E4%7D%20-%20x%5Csqrt%7B5x%5E2%7D%20%20%29)
On simplifying, we have
![\rm 4\sqrt{2} (x)^{\frac{3}{2}} * ( 3\sqrt{10} x^2 - \sqrt{5} x^{\frac{3}{2}})\\\\24\sqrt{5} x^{\frac{7}{2}} - 4\sqrt{10}x^3\\\\4\sqrt{5}x^3(6\sqrt{x} -\sqrt{2} )\\](https://tex.z-dn.net/?f=%5Crm%204%5Csqrt%7B2%7D%20%20%28x%29%5E%7B%5Cfrac%7B3%7D%7B2%7D%7D%20%2A%20%28%203%5Csqrt%7B10%7D%20x%5E2%20-%20%5Csqrt%7B5%7D%20x%5E%7B%5Cfrac%7B3%7D%7B2%7D%7D%29%5C%5C%5C%5C24%5Csqrt%7B5%7D%20x%5E%7B%5Cfrac%7B7%7D%7B2%7D%7D%20%20-%204%5Csqrt%7B10%7Dx%5E3%5C%5C%5C%5C4%5Csqrt%7B5%7Dx%5E3%286%5Csqrt%7Bx%7D%20-%5Csqrt%7B2%7D%20%29%5C%5C)
