Evaluate.
NikAS [45]

The value of the expression [(114−34)⋅(−23)3]÷(−4) is equal to the fraction 5451/4 or the mixed fraction 1362 whole number, 3/4.

<h3>Evaluation for the expression considering PEDMAS</h3>

P – Parenthesis First: B – Brackets First

E – Exponents

D – Division

M – Multiplication

A – Addition

S – Subtraction

We evaluate the expression [(114−34)⋅(−23)3]÷(−4) as follows;

114 - 34 = 79

-23 × 3 = -69

so;

[(114−34)⋅(−23)3] = 79 × −69

[(114−34)⋅(−23)3] = −5451

[(114−34)⋅(−23)3]÷(−4) = −5451/−4

divide through by the common factor −1

[(114−34)⋅(−23)3]÷(−4) = 5451/4

Therefore, the simplified value for the expression [(114−34)⋅(−23)3]÷(−4) is the fraction 5451/4 or the mixed fraction 1362 whole number, 3/4
