Perform the following calculations without rewriting the numbers in decimal form
(6 × 10^11)(2.5 × 10^−5)

15×10⁶

Step-by-step explanation:

We are given the following expression (6×10¹¹)(2.5×10⁻⁵).

It is asked in the question that to calculate the above expression provided we can not write the numbers in decimal form.

Now, the given expression

(6×10¹¹)(2.5×10⁻⁵)

{Since all the numbers in the above  are in product form so we can rearrange the terms}

= (6×2.5)(10¹¹×10⁻⁵)

= 15×10⁽¹¹⁻⁵⁾

{Since we know the property of exponent that xᵃ.xᵇ =x⁽ᵃ⁺ᵇ⁾ }

=15×10⁶ (Answer)

4 + 5 7/9= 9 7/9
