1,000,000 Decimal form avoids fractions. For example, 1/2 is .5 in decimal form. 10^6 is 10x10x10x10x10x10. This is 1,000,000. (Since you are multiplying tens, you can just add the zeros together.)
For a negative power of -k, the equivalent decimal is the decimal point followed by (k-1) zeros followed by 1.Thus 10^-5 = 0.00001
t That reduces to 1 1/10 which equals 1.1 in decimal form.
10 ^ -3 = 1/1000 = 0.001. Times 3.2 = 0.0032
10
example 0.0081 the exponential form is (8 times 1/10 raise to the third power)+(1 times 1/10 raise to the fourth power)
decimal form of 10 tenths = 1.010 tenths in decimal = 1
1,000,000 Decimal form avoids fractions. For example, 1/2 is .5 in decimal form. 10^6 is 10x10x10x10x10x10. This is 1,000,000. (Since you are multiplying tens, you can just add the zeros together.)
It is: 1 and 3/10 = 1.3 in decimal form
For a negative power of -k, the equivalent decimal is the decimal point followed by (k-1) zeros followed by 1.Thus 10^-5 = 0.00001
Standard form requires a single non-zero digit before the decimal point and a multiplier of a power of 10 which gets the decimal point back to where it was in the original number. To calculated the power of the ten count how many digits the decimal point needs to move; if it needs to move to the left make it negative: 0.56 → 5.6 × 10^-1
1 2/10 or 12/10 can be written as 1.2 in decimal form
It is 0.1
t That reduces to 1 1/10 which equals 1.1 in decimal form.
In standard form it is 1*10^1.
The fraction one tenth (1/10) has the decimal form 0.1
