Write the decimal or enter it into your calculator.
Write a multiplication problem in which you multiply the decimal times itself the number of times indicated by the exponent, or you can enter the "*" or "x" symbol on your calculator followed by the decimal number again. For example, if you have 0.525^2, you would set up the multiplication problem 0.525 x 0.525.
Press the equal key (=) on your calculator or multiply the two decimal values by hand to find your answer. In this example, if you multiply 0.525 times 0.525, you will get the answer 0.275625.
Multiply series of decimals that possess like bases by retaining the base and adding the exponents. For example, if you have 0.525^3 x 0.525^2 x 0.525^2, your answer could be simplified to 0.525^7 (since the exponents equal 7 when added together). If you want the exact answer for this once you've added the exponents, you can use a calculator with an exponent function that reads "x^y." You would enter "0.525," then "x^y," "7" and the "=" sign to view the answer. You could multiply this by hand, but it would take a bit of time and effort. You also can use online exponent calculators (see Resources). The final answer to this particular example would be 0.010993.
