ANSWER THIS AS GIVEN PLEASE

x = 1

Step-by-step explanation:

Apply the exponent rule for multiplication, add the exponents

Convert 81 into exponential form with a base of 3

3*3*3*3=81

3^4=81

Since the bases are the same, set the exponents equal

3x+1=4

3x=3

x=1

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
