The standard (or scientific) notation comes in two parts:
the mantissa, a is a number such that 1 ≤ a < 10
and the exponent, b, which is an integer.
Given any number, write it so that the decimal point is after the first non-zero digit. Next, calculate the number of digits that you moved the decimal point. The number of places determines the value of b. If you moved the decimal point to the left then b is positive, if to the right, b is negative and if you did not move it at all, b is 0.
Examples:
2345.678 = 2.345678*103
0.00234 = 2.45*10-3
0.3
6,700,000
Either 1,600,000 or 1.6 X 106.
The decimal 7.24 in standard form is 7.24 × 100
That is the standard form.
In standard form it is 1*10^1.

To write 29 hundredths in standard form, you would express it as a decimal number. 29 hundredths is equivalent to 0.29 in decimal form. In standard form, you would write this as 0.29.
51 billion in decimal or standard form is 51,000,000,000
