Which is the simplified form of the expression

B. 1/(x^21y^12)

Step-by-step explanation:

First solve of x:

x^-3 / x^4 is same thing as 1/ x^3x^4 which is equal to 1/x^7

Now the cube part: (1/x^7)^3 = 1/x^21

Solve for y:

y^2 / y^6

1/ y^-2y^6 = 1/y^4

(1/y^4)^3

1/y^12

1/(x^21y^12)

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
