Question

What is the qoutient?

Answer 1

Answer:

Option (3)

Step-by-step explanation:

Given expression is,

(6 × 10⁸) ÷ (1.5 × 10⁻⁴)

We can rewrite the given expression as,

$\frac{6\times 10^8}{1.5\times 10^{-4}}$

Now by solving this expression further,

$\frac{6\times 10^8}{1.5\times 10^{-4}}=\frac{6}{1.5}\times \frac{10^8}{10^{-4}}$

             $=4\times 10^8\times 10^4$ [Since $\frac{1}{10^{-4}} =10^4$]

             = $4\times 10^{(8+4)}$

             = $4\times 10^{12}$

Therefore, Quotient of the given expression is $4\times 10^{12}$.

Option (3) will be the answer.
