Final answer:
The calculation of 2x10+6x1+3x1/100+9x1/1000 results in adding 20, 6, 0.03, and 0.009 together, which gives a final sum of 26.039 in decimal form.
Step-by-step explanation:
To calculate 2x10+6x1+3x1/100+9x1/1000 in decimal form, you simply perform each multiplication and addition step by step. Starting with 2x10, which equals 20. Next, you have 6x1, which equals 6. Then address the decimal multiplications: 3x1/100 is 0.03 because you are moving the decimal two places to the left, and 9x1/1000 is 0.009, moving the decimal three places to the left. Adding these results together, you get 20 + 6 + 0.03 + 0.009, which sums up to 26.039. This operation demonstrates how to handle powers of ten and basic arithmetic to achieve a final result in decimal form.
