How many bits are in 1 Tb? [Depending on the tool used to calculate this, you may need to use a trick to get the exact result. Note that 2²⁰ = 1,000,000₁₀ + d, where d is the difference between 2²⁰ and 1,000,000₁₀, and that 1T = (1,000,00010 + d)². Expand the equation for 1T into a sum-ofproducts form, insert the value of d, ind the three products, and then ind their sum.]
