write the number 890,000 in scientific notation?

Answer 1

8.9 x 10^5

Answer 2

Scientific notation means

a x 10^b

where 1 < a < 10 and b is a real #.

So it would be 8.9 x 10^5.

Answer 3

The answer is 8.9x10 to the 5th

Scientific notation is written as a number between 1 and 10 multiplied by a specific power of 10. A power of 10 is 10 multiplied by itself a certain number of times. For example, 10 × 10 × 10 is 10 to the third power, or 103. The number 3 in this notation is an exponent and indicates the number of times 10 should be multiplied by itself. Writing numbers in scientific notation allows scientists to leave out a number of zeros while still retaining some indication that the zeros exist. The number 71,000, for example, is the same as 7.1 multiplied by 10,000 (104) and is written 7.1 × 104 in scientific notation. Numbers smaller than 1 have negative exponents in scientific notation. The number 0.00523, for instance, is the same as 5.23 times 0.001 (10-3) and is written 5.23 × 10-3. 10-3 means 1 divided by (10 × 10 × 10).

Scientific notation is especially useful in writing or reading extremely large or small numbers. The weight of a single atom of hydrogen, for example, is about 1.7 × 10-24 or 0.0000000000000000000000017 grams.

Answer 4

OK!

Scientific notation uses powers of ten to simplify large numbers. (Lots of zeros get confusing.) So count back decimal places until you get a ones place and one-tenths place (here 8.9). That is five places, so the expression is:
8.9 X 10^5

Double-check: 10^5 is indeed 100,000, so it makes sense.

Answer 5

8.9 x 10^5

Answer 6

1)First you have to move the decimal point however many places to make it a number between 1-10.
2)Then count how many places you moved it and put that as a power of 10.
1)8.9
2)8.9X10^5

Answer 7

8.9 E5

Answer 8

is that 800000 +90000?

Answer 9

890,000 =8.9*10^5
