Answer:
An algebraic expression is an expression built up from constants,variables, and the algebraic operations.for example:3x^2-2xy+c is an algebraic expression.
 
        
                    
             
        
        
        
<span>5.5*10^5 = 550,000 tons
</span><span>$23,000 per ton 
</span>
23,000 x 550,000 = <span>$12,650,000,000 (total value)
</span>Now to convert to scientific notation.
<span>1.265 x 10^10
</span>

To perform the following operation, make sure to do the division parts separately and place them back together in the final answer. 
10/2 and x^5/x^2 
5 and using the exponential laws of division X ^m/X^n = X ^ m-n 
The second part evaluates to X^3. 
Putting the terms together we get the final answer, which is 5x^3.
