Standard Form b Example
1. Standard A ×10 8400 = 8.4 x 103
Form
where 1≤ A<10 , b=integer 0.00036 = 3.6 x 10−4
2. Multiplying Multiply: Multiply the numbers and add ( 1.2 ×103 ) × ( 4 ×10 6 )=8.8 × 109
or Dividing the powers.
with Standard Divide: Divide the numbers and subtract ( 4.5× 105 ) ÷ ( 3× 102 )=1.5 ×10 3
Form the powers.
3. Adding or Convert in to ordinary numbers, calculate 4
2.7 ×10 +4.6 × 10
3
Subtracting and then convert back in to standard form ¿ 27000+ 4600=31600
with Standard ¿ 3.16 ×10
