Answer:
 (9x²)²
Step-by-step explanation:
Given the expression 81x⁴, to write the expression as a square of a monomial, first we will assign a variable to the expression.
y = 81x⁴
Then we take the square root of both sides of the expression
√y = √81x⁴
y^½ = √81 × √x⁴
y^½ = 9x²
Squaring both sides of the resulting equation to get y back
(y^½)² = (9x²)²
y = (9x²)²
The expression as a square of a monomial is (9x²)²
 
        
                    
             
        
        
        
The answer is Angle Y equals 138. 
angle y= 180 -42 which gives u 138

Answer:
m<G = 71
Step-by-step explanation:
Find x first 
7x + 1 + 6x - 6 + 55 = 180 
Combine like terms:
13x + 50 = 180 
       - 50    - 50 
13x = 130 
/13     /13 
x = 10 
Then apply to problem 
7 (10) + 1 
70 + 1 
= 71
