A theory states that the cpu clock speed in a computer doubles every 18 months. if the clock speed was 33 MHz in 1991, how can you use exponents to find out how fast the clock speed is after doubling three times

The simple way to double something more than once is to multiply the original number by 2 and then double the product until the final amount of doubles has been reached, in this case, 3. Doubling 33 3 times, we get 264
