C and D are irrational.

Generally, any square root that doesn't reduce to a rational number is irrational. Some examples:

• √2 is irrational

• √4 = 2 is rational

• √(1/2) = 1/√2 = √2/2 is irrational

• √(1/9) = 1/√9 = 1/3 is rational

Numbers with non-terminating decimal expansions are rational if there is a repeating pattern after the decimal. The pattern in 4.737737773… is pretty obvious (one 7, one 3, two 7s, one 3, three 7s, one 3, etc) but it does not repeat, the number of 7s just keeps going up. Compare this to 4.737373… or 4.773773773… - these two numbers are rational in contrast.

Simplify 27x^7y^2/9x^6y^5
solmaris [256]

Answer: x/y^3

Step-by-step explanation:

So you divide 27/9 which is 3. Then it ix x^7-x^6=x. And then it is y^2-y^5=y3

27*x*x*x*x*x*x*x*y*y/9*x*x*x*x*x*x*y*y*y*y*y

Doing this makes it easier so you cross each variable out for each one in both sides. 3x/y^3 would be your answer.

Solve 6(x+1)3−10=740
Vera_Pavlovna [14]

Answer:

x=122/3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6(x+1)(3)−10=740

18x+18+−10=740(Distribute)

(18x)+(18+−10)=740(Combine Like Terms)

18x+8=740

18x+8=740

Step 2: Subtract 8 from both sides.

18x+8−8=740−8

18x=732

Step 3: Divide both sides by 18.

18x

18

=

732

18

x=

122

3

Answer:

x= 122/3
