The exponent is an unknown variable. It is a variable because it will change into a known number when we get further into the equation.
Take this for example.
4x=8 - where x is the exponent.
To work out the problem we simply move the 4 over the equal's sign. Since it is 4x, this means that it is 4 times x. Since we are moving the 4 over the equals sign, we have to change the multiplication, into a division.
x=8/4 which equals 2. The x is a 2.
To check, we we substitute the 2 with the x in the equation. 4x2=8, which is correct.

When dividing in scientific notation what do you do with the exponents?
You subtract the exponent of the denominator from that of the numerator.
When 508000000 is written in scientific notation what will be the value of the exponent?
It is: 5.08*10^8 in scientific notation and the exponent of 10 is 8
What is the value of the exponent in the scientific notation expression for the number 6140000000?
The value of the exponent is 9: (6,140,000,000 in Scientific Notation = 6.14 x 109)
Do you express scientific notation?
Scientific Notation is expressed by using a number, using an exponent as a number (usually a decimal) multiplied by a 10, and an exponent (the number on the exponent is the number of zeros the number has).Example: 120,000,000 in scientific notation is 1.2 X 107
What is the value of the exponent in the scientific notation expression for the number 0.00207000?
It is: 2.07*10^-3 in scientific notation
