Answer 2

Answer :

10 ⁹ × 3² = 9,00,00,00,000 .

Step by step explanation :

Hey Mate,

• Square = X × X = X ²   #(Square of negative number always be Positive)

• Power 9 = X × X × X..... upto 9 times = X ⁹

3 ² = 3 × 3 = 9

10 ⁹ = 1,00,00,00,000

Eq : 10 ⁹ × 3²

= >  1,00,00,00,000 × 9

= > 9,00,00,00,000 .
