Question

Convert 1.5 × 108 from scientific notation to standard form. 15,000,000 150,000,000 1,500,000,000 15,000,000,000

Answer 1

Step-by-step explanation:

We need to convert 1.5 × 10⁸ from scientific notation to standard form.

The scientific notation is 1.5 × 10⁸

Out of the given options, we need to choose the correct one.

10⁸ means 100000000

⇒ $1.5\times 10^8=1.5\times 100000000$

or

$1.5\times 100000000=\dfrac{15}{10}\times 100000000$

One of the zero from denominator and numerator will cancel down.

$\dfrac{15}{10}\times 100000000=15\times 10000000\\\\=150000000$

So, the correct option is b.
