Answer:
Step-by-step explanation:
Exponents with fractions in them are really just radical notation in a different form. You've probably seen the square root sign.
That can be written as 
x^(1/2)
...and when you take an even root of a negative number, there is no real answer. (2 is an even number).
Looking at the answer choices here, we can see that B and D use even roots, so they will give non-real answers.
So, A and C are the answer choices to select.
 
        
                    
             
        
        
        
Answer:
x = 13y + 0.625
Step-by-step explanation:
4(2x - 3y) = y + 5
8x - 12y = y + 5
8x = y + 5 + 12y
8x = 5 + 13y
8x ÷ 8 = 5 + 13y ÷ 8
x = 5 + 13y ÷ 8
x= 13y + 5 ÷8
x = 13y + 0.625
 
        
             
        
        
        
Answer:
1/r^56
Step-by-step explanation:
Not sure if you did a typo there or what cus 7 x 8 should be 56
Whenever the power of a number is negative, you flip. So r^-7 becomes 1/r^7
Remove the bracket and distribute 8 to the power of 1 and r^7
1 to the power of 8 will still be 1, r^7 x 8 = r ^ 56
