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

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
