Evaluate x5-13 if x =-2
-32 - 13
I don't get it
We assume you mean -2 to the 5th power.
-2 * -2 * -2 * -2 * -2 = -32
x to the 5th power = x^5
To evaluate x^5 - 13 when x = -2, we will substitute -2 for x in the expression and perform the calculations.
So, let's substitute -2 for x in the expression x^5 - 13:
(-2)^5 - 13
First, calculate -2 raised to the power of 5:
(-2) × (-2) × (-2) × (-2) × (-2)
= -32
Now substitute this value back into the expression:
-32 - 13
Finally, perform the subtraction:
-32 - 13 = -45
Therefore, x^5 - 13 when x = -2 is equal to -45.
