Need to multiply by 2 * 3²  with 2⁹⁸   * 3⁴⁶

Step-by-step explanation:

Taking both term separate  

2⁹⁸   * 3⁴⁶     and   2¹⁰⁰  * 3 ²⁰⁰

2 & 3 are co-prime

2⁹⁸   * 3⁴⁶

= 2⁹⁶ * 2²   * 3⁴⁵ * 3

= (2³²)³ * 2² * (3¹⁵)³ * 3

To make it perfect cube

we need to multiply by 2 * 3²

= (2³²)³ * 2² * (3¹⁵)³ * 3  * 2 * 3²

= (2³²)³ * 2³ * (3¹⁵)³ * 3³

= (2³³)³ * (3¹⁶)³

= ( 2³³ * 3¹⁶)³

2¹⁰⁰  * 3 ²⁰⁰

= 2⁹⁹ * 2 * 3¹⁹⁸ * 3²

= (2³³)³ * 2 * (3⁶⁶)³ * 3²

To make it perfect cube

we need to multiply by 2² * 3

= (2³³)³ * 2 * (3⁶⁶)³ * 3²  * 2² * 3

= (2³³)³ * 2³ * (3⁶⁶)³ * 3³

= (2³⁴)³ * (3⁶⁷)³

= (2³⁴ * 3⁶⁷)³
