Answer:
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)
