Answer explanation

write 1,000,000 in scientific notation

Answer explanation

since the number is 1,000,000 we add a decimal at the end 1,000,000.0- then we move that decimal point till we have 1.0 - so how many times did we move the decimal? 6 times wow your smart. so to put that in scientific notation we write it as 1.0x10^6

scientific notation always is Ax10^b

A being the number we get with the decimal and b being how many times we moved the decimal point

what is 0.000000124 in scientific notation

• 1.24x10^7

• 124x10^7

• 1.24x10^-7

• 124x10^-7

Answer explanation

so we have 0.000000124 oh my what a scary number. this time we will move the decimal point to the RIGHT since the first number greater than zero is on the right. so we move it till we have 1.24. how many times did we move it to the right ? 7 times yay! but since we moved the decimal to the RIGHT its a NEGATIVE exponent. so to write it we do 1.24x10^-7

what is 1.742x10^3 in a regular number

• 174.2

• 1.7423

• .001742

• 1742

Answer explanation

ooh plot twist right well for this one we work backwards 1.742x10^3

so we know 3 is positive so we have to move the decimal back to where it was meaning to the right so we count 3 spaces to the right being 1742

you have to do the opposite to get it back to normal
