Question

Perform the following calculations without rewriting the numbers in decimal form.

Answer 1

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)

=$\frac{1.42*10^{-50} }{2*10^{13} }$ {All the terms are in product form, so we can rearrange this}

=($\frac{1.42}{2}$)($\frac{10^{-50} }{10^{13} }$)

=(0.71)($10^{-50-13}$) {We know the formula of indices $\frac{x^{a} }{x^{b} }=x^{(a-b)}$}

=0.71×10⁻⁶³ (Answer)
