Answer 2

Step-by-step explanation:

Given :-

6.4 x 10¹² - 42 x 10¹⁰

To find :-

Simplify the expression ?

Solution :-

Given expression is 6.4 x 10¹² - 42 x 10¹⁰

=> (64/10)×10¹² - 42×10¹⁰

=> 64×(10¹²/10) - 42 × 10¹⁰

=> 64 × 10¹²-¹ - 42 × 10¹⁰

Since a^m / a^n = a^(m-n)

=> 64 × 10¹¹ - 42 × 10¹⁰

=> 64 × 10 × 10¹⁰ - 42 × 10¹⁰

=> 640 × 10¹⁰ - 42 × 10¹⁰

On taking 10¹⁰ as common then

=>(640-42) × 10¹⁰

=> 598 × 10¹⁰

Answer:-

The Value of the given expression is

598 × 10¹⁰ or 5980000000000

Used formulae :-

• a^m / a^n = a^(m-n)

• a^m × a^n = a^(m+n)
