1.which of the following rational exponent expressions is not simplified correctly as a radical expression?
2. simplify the rational exponent expression as a radical expression. (729x^3y^-18)^1/6
*answer choices in linked pics*

1) Option A) is correct

The given rational exponent expression is not simplified correctly as a radical expression is

2)Option A) is correct

That is

Step-by-step explanation:

1) Given that

is the correct answer but in the given problem they gave the RHS as wrong.

Therefore the given rational exponent expression is not simplified correctly as a radical expression is

2)Given that the rational exponent expression is

To find it as a radical expression:

Therefore

Therefore Option A) is correct

That is

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

i believe the answer is d.

hope it you! : d
