![]() ![]() Means \(3 \times 3 \times 3 \times 3 \times 3\). The seventh power of 2 is shown in questionĤ(d).What power of 2 is shown in each of the following parts of question 4? \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2\)īecause the factor 2 is repeated 5 times, 32 is calledġ25 can also be called "5 to the power 3" or "5 cubed". \times 2 \times 2 \times 2 \times 2 \times 2 \times 2\) \( 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2\) Repeated as a factor and how many times it is repeated.Ī number that can be expressed as a product of one repeated factor is called a power of that number. Numbers in question 1 have repeated factors? In each case, state what number is Example: \(250 = 2 \times 5 \times 5ĥ is a repeated factor of 250. The exponential notation Repeated multiplication with the same numberīelow as a product of prime factors. That when you add their squares, you get the square of another number? Two numbers, so that the square of the one number is equal to the cube of the Instead of saying "10 times 10 times 10", we may say "10 cubed" and we may write 10 3. ![]() ![]() ![]() Ten", we may say "ten squared" and we may write \(10^2\). 3 3 3 3 3 3 3 3 3 3 3 3 3\) Quick squares and cubes Again and again You already know a short way to describe calculations like this: \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3\) \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 For i i i, r = ∣ i ∣ = 1 r=|i|=1 r = ∣ i ∣ = 1 and θ = arccot ( 0 1 ) = π 2 2 k π \theta=\text − 2 3 2 i , and − i -i − i.In this chapter, you will learn about a very short way to describe calculations like this: First, it is necessary to write the complex number in polar form. ![]()
