Question

Match the following items by evaluating the expression for x = -7. x-2 x-1 x0 x1 x2

Answer 1

`{x}^( - 2) = \frac{1}{ {x}^(2) } \: \: –> {7}^( - 2) = \frac{1}{ {7}^(2) } = ( 1)/(49) \\ \\ {x}^( - 1) = \frac{1}{ {x}^(1) } \: –> {7}^( - 1) = \frac{1}{ {7}^(1) } = (1)/(7) \\ \\ {x}^(0) –> {7}^(0) = 1 \\ \\ {x}^(1) –> {7}^(1) = 7 \\ \\ {x}^(2) –> {7}^(2) = 49`
