Solution

To simplify the expression 3x22y43y2 .

  3x4y2

Given:

The expression, 3x22y43y2 .

Concept Used:

Exponent Properties:

  • Product property: aman=am+n
  • Quotient property: aman=amn
  • Power of a power property: amn=amn
  • Power to product property: abn=anbn
  • Negative exponent property: an=1an

Calculation:

In order to solve the given expression 3x22y43y2 , use the exponent properties and simplify further as shown below,

  3x22y43y2=32x22y43y2=9x4y43y2=93x4y4y2=3x4y42=3x4y2=3x4y2

Therefore, the simplified expression is 3x4y2 .
