Answer 1

Answer:

Step-by-step explanation:

2) 15⁴ * 18³/3³ * 5² * 12²

=> (3*5)⁴ * (2*3²)³/3³ * 5² * (3*2²)²

Using identities (ab)ⁿ = aⁿ * bⁿ , (xᵃ)ᵇ = xᵃᵇ

=> 3⁴ * 5⁴ * 2³ * 3⁶ / 3³ * 5² * 3² * 2⁴

Using identity xᵃ * xᵇ = xᵃ⁺ᵇ

=> 3⁴⁺⁶ * 5⁴ * 2³ / 3³⁺² * 5² * 2⁴

=> 3¹⁰ * 5⁴ * 2³/3⁵ * 5² * 2⁴

Using identity xᵃ / xᵇ = xᵃ⁻ᵇ

=> 3¹⁰⁻⁵ * 5⁴⁻² / 2⁴⁻³

=> 3⁵ * 5²/2

3) The standard form is 5.69208 * 10⁸
