WebMay 1, 2024 · Evaluate 9x − 2, when x = 5 x = 1 Solution Remember ab means a times b, so 9x means 9 times x. To evaluate the expression when x = 5, we substitute 5 for x, and then simplify. To evaluate the expression when x = 1, we substitute 1 for x, and then simplify. Notice that in part (a) that we wrote 9 • 5 and in part (b) we wrote 9(1).

Web9 to the power of 2 = 9 2 = 81 Why do we use exponentiations like 9 2 anyway? Well, it makes it much easier for us to write multiplications and conduct mathematical operations … WebFirstly, a power shows how many times a number is multiplied by itself. For example, if we take the number 2 raised to the power of 2, or squared (written like this: 2^2), we get an answer of 4. This is because 2 x 2 = 4, so we have multiplied 2 by itself twice. Numbers can be raised to any power, even infinity. WebFirst things first, depends on the expression. You would either get a solution with i, or you'd get a rational number. Let's take your example: (-625)^ (3/4) Best way to approach this is to split it up, remember that: ab² = a²b² (² being an example) -1^ (3/4) * 625^ (3/4) Looking at 625, it can be broken down into: 5⁴ Using (aᵇ)ᶜ = aᵇᶜ: asian dating venture
