QuestionCube -5 and subtract from -18. Simplify: -18 - (-5)^3.

Studdy Solution

STEP 1

Assumptions1. The number to be cubed is -5. The number from which the cubed result will be subtracted is -183. The order of operations (PEMDAS/BODMAS) will be followed, where/B - Parentheses/Brackets first/O - Exponents/Orders (ie Powers and Square Roots, etc.) MD - Multiplication and Division (left-to-right) AS - Addition and Subtraction (left-to-right)

STEP 2

First, we need to cube -5. Cubing a number means multiplying the number by itself twice.
$Cube\, of\, -5 = (-5) \times (-5) \times (-5)$

STEP 3

Calculate the cube of -5.
$Cube\, of\, -5 = (-5) \times (-5) \times (-5) = -125$

STEP 4

Now that we have the cube of -, we can subtract this from -18.
$Result = -18 - (-125)$

STEP 5

Remember that subtracting a negative number is the same as adding a positive number.
$Result = -18 +125$

STEP 6

Calculate the result.
$Result = -18 +125 =107$ The numerical expression is107.
