To find the nth power of number x, you multiply n x's together. In this case we want the 4th power of 10, so we take 4 10s (10, 10, 10, 10) and multiply them together: 10x10x10x10=10,000 So 10 to the 4th power is 10,000.
To calculate this, write the number as a power of ten, and use the fact that when you raise a power to a power, you simply multiply the exponents. (10^10)100 = 10^20
Move the decimal point, the same number of places as the power of 10. That way ---> to multiply. This way <--- to divide.
10 to the 17th power.
Apart from using a calculator, specifically if you multiply a whole number by a power of 10:* To multiply a whole number by 10, add a zero to the whole number. * To multiply a whole number by 100, add two zeros to the whole number. * Etc.
