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)
=[tex]\frac{1.42*10^{-50} }{2*10^{13} }[/tex] {All the terms are in product form, so we can rearrange this}
=([tex]\frac{1.42}{2}[/tex])([tex]\frac{10^{-50} }{10^{13} }[/tex])
=(0.71)([tex]10^{-50-13}[/tex]) {We know the formula of indices [tex]\frac{x^{a} }{x^{b} }=x^{(a-b)}[/tex]}
=0.71×10⁻⁶³ (Answer)
