How can you use an exponent to show powers of 10?
The exponent in this case is the small number written in superscript (raised) to the right of the 10.
Is 10 to the negative 4th power a positive number?
Yes. Any positive number to an exponent is positive.
How do you change powers in scientific notation?
To change a number from standard to scientific notation, move the decimal point to create a number between 1 and 10. Count the number of places you moved the decimal point to get the power of 10. If you moved it to the left, the exponent is positive, and if you moved it to the right, the exponent is negative.
What number of digits when 10 to the 23th power that written in full?
24: the number of digits is always one more than the exponent of 10 if the exponent is positive.
What is 2.5 x 10 exponent -4 expanded into powers of ten such as 2.5 x 10 exponent 4 2.5 x 10 x 10 x 10 x 10?
It is 2.5/(10*10*10*10) or 2.5*0.0001
When is the exponent positive?
An exponent is positive when the number being raised to that exponent is greater than 0. For example, in the expression 2^3, the exponent is positive because 2 is a positive number.
What does it mean to have a positive exponent?
An exponent tells how many times the base is used as a factor. 10^3 = 10 x 10 x 10
How can you use an exponent to show powers of 10?

Is 10 to the negative 4th power a positive number?
Yes. Any positive number to an exponent is positive.
What does it mean when an exponent is a negative number?
A negative exponent is the reciprocal of the corresponding positive exponent. 102 = 100 10-2 = 1/100

What is 2.5 x 10 exponent -4 expanded into powers of ten such as 2.5 x 10 exponent 4 2.5 x 10 x 10 x 10 x 10?
It is 2.5/(10*10*10*10) or 2.5*0.0001
What are the powers of 10?
10, 100, 1000, 10000, ... are the positive powers. 0.1, 0.01, 0.001, ... are negative powers.
What does a positive exponent mean used in scientific notation?
A positive exponent means that decimals are added to the right of the base number. So 10 X 53 would be 5000. 10 X 5-3 would be .0005
Some of the numbers in scientific notation have a negative exponent and some have a positive exponent. Explain the difference between these tow types of numbers.?
The mantissa is multiplied by 10 raised to the power as shown by the exponent. So, if the exponent is 4, then you multiply the mantissa by 10^4 = 10,000. If the exponent is -4 then you multiply the mantissa by 10^(-4) = 0.0001 or, equivalently, divide by 10^4.
How do you change negative exponents to positive exponents?
If you have 10^-3 then you can consider it the same as (1/10^3) and you have changed the negative exponent to positive exponent. Similarly, if the original number is (1/10^-3), that is equivalent to 10^3. In most cases it is as simple as taking the reciprocal.
