if 22000 pots with 15 seeds each are used in a nursery, how many total seeds, in scientific notation?
kipiarov [429]

Write the total number of seeds in scientific notation

Given:

Number of pots = 22,000

Number of seeds = 15

<em>Total number of seeds = Number of pots × Number of seeds</em>

= 22,000 × 15

= 330,000

Scientific notation is written in multiples of 10

  • Count the number of digits
  • Insert a decimal point between the first digit and other digits
  • count the number of digits after the first digits
  • multiply by 10 raise to the power of number of remaining digits after first digits

= 3.30000 × 10^5

Therefore,

the total number of seeds in

scientific notation is 3.30000 × 10^5
