What is the value of the expression 246×22×32(2)3\frac{-2^4 - 6 \times |2 - 2 \times 3|}{2 - (-2)^3} ?

Cevap: -4

Cevap

The value of the expression is 4-4.
Evaluating the expression step-by-step using order of operations (PEMDAS) yields 4-4. First, simplifying the absolute value 22×3|2 - 2 \times 3| gives 44. Next, the exponent 24-2^4 evaluates to 16-16, and the exponent (2)3(-2)^3 in the denominator evaluates to 8-8. The numerator simplifies to 166(4)=40-16 - 6(4) = -40, and the denominator simplifies to 2(8)=102 - (-8) = 10. Finally, division gives 40÷10=4-40 \div 10 = -4.

Adım Adım Çözüm

1
Simplify the absolute value expression in the numerator
22×3=4=4|2 - 2 \times 3| = |-4| = 4
By the order of operations, multiplication must be performed before subtraction inside the grouping symbols (absolute value).
2
Evaluate the exponential terms in the numerator and denominator
24=16-2^4 = -16 and (2)3=8(-2)^3 = -8
In the term 24-2^4, the negative sign is not grouped with the base, so it evaluates to (2×2×2×2)=16-(2 \times 2 \times 2 \times 2) = -16. In (2)3(-2)^3, the base is negative, evaluating to (2)×(2)×(2)=8(-2) \times (-2) \times (-2) = -8.
3
Calculate the final values of the numerator and the denominator
Numerator = 40-40, Denominator = 1010
For the numerator, perform the multiplication before the subtraction: 16(6×4)=1624=40-16 - (6 \times 4) = -16 - 24 = -40. For the denominator, subtract the negative number: 2(8)=2+8=102 - (-8) = 2 + 8 = 10.
4
Divide the numerator by the denominator
4-4
The quotient of 40-40 and 1010 is 4-4.
