Answer:
0.71×10⁻⁶³
Step-by-step explanation:
Here in this problem, the expression (1.42×10⁻⁵⁰) / (2×10¹³) is given and we have to calculate the result not rewriting the numbers in decimal form.
Now, the given expression,
(1.42×10⁻⁵⁰) / (2×10¹³)
= {All the terms are in product form, so we can rearrange this}
=()()
=(0.71)() {We know the formula of indices }
=0.71×10⁻⁶³ (Answer)
