Answer:
[tex]\color{skyblue}\boxed{x = 1500000 × 20⁹/23⁹}[/tex]
Step-by-step explanation:
Based on the given conditions, formulate:
- x × (1+15%) ⁹ = 1500000
Calculate the sum or difference:
- x × 1.15 ^ 9 = 1500000
Divide both sides of the equation by the coefficient of variable:
- x = 1500000/1.15⁹
Convert decimal to fraction:
- x = 1500000/ (115/100)⁹
Cross out the common factor:
- x = 1500000/ (23/20)⁹
Simplify using exponent rule with same exponent:
- (ab)n =an.bn: x = 1500000/23⁹/20⁹
Divide a fraction by multiplying its reciprocal:
- x = 1500000 × 20⁹/23⁹
Write as a single fraction:
- x = 1500000 × 20⁹/23⁹
Gets the result:
- x = 1500000 × 20⁹/23⁹
