Question

solve the given exponential equation ​

Answer 1

Step-by-step explanation:

x+3/9=2/3

3(x+3)=9*2

3x+9=18

3x=18-9

3x=9

x=9/3

x=3

Answer 2

Answer:

n = -2

Step-by-step explanation:

9ⁿ⁺³ = 3²

⇒(3²)ⁿ⁺³ = 3²

⇒3²ⁿ⁺⁶ = 3²

⇒2n + 6 = 2

⇒2n = 2 - 6 = -4

⇒n = -2

Answer⇒ n = -2

Verification:-

9ⁿ⁺³ = 3²

• Substitute n = -2

9⁻²⁺³ = 3²

⇒9¹ = 3²

⇒9 = 9

Hence, verified.
