Power Multiplication Math
In this example the little 2 says to use 8 two times in a multiplication.
Power multiplication math. When there s no exponent showing such as with y you assume that the exponent is 1 so in the above example you write. If there s more than one base in an expression with powers you can combine the numbers with the same bases find the values and then write them all together. It is written as a small number to the right and above the base number. In our example the first power has an exponent of 2.
Xm n x m n if you have a product inside parentheses and a power on the parentheses then the power goes on each element inside. Find the exponent of the first power. The power or exponent of a number says how many times to use the number in a multiplication. Whenever you have an exponent expression that is raised to a power you can simplify by multiplying the outer power on the inner power.
In our example the second power has an exponent of 3. Multiplying by powers of ten follow the following useful and easy shortcuts when multiplying by powers of ten. For example here s an example with a number that has no exponent showing. Whole numbers multiplied by powers of 10 when multiplying a whole number by a positive power of ten just count how many zero s you have and attached that to the right of the whole number.
