a. 8ab

b. y^3

c. e/f

Step-by-step explanation:

a; a * b * 8 = 8ab

b. y * y * y = y^3

c. we cancel out the e and f

e^4/e^3 * f/f^2

= e/f

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
