Express the following numbers in standard form:

24 billion

For the standard form notation, only one number is kept before the decimal point and rest all numbers are written after decimal point.

The power of 10 denotes the number of terms shifted after the decimal point.

So for 24 billion = 24,000,000,000

Here only one number will be kept before decimal point that is 2.

Number of terms to be shifted after decimal point = 10

24,000,000,000 = 2.4 × 10¹⁰
