Cevap

12
Evaluating the first term gives 16, and evaluating the second term gives 4. Subtracting 4 from 16 results in the correct value of 12.

Adım Adım Çözüm

1
Evaluate the first term: 22×232\frac{2^2 \times 2^3}{2}
16
According to the product rule of exponents, 22×23=22+3=25=322^2 \times 2^3 = 2^{2+3} = 2^5 = 32. Dividing this by the denominator yields 32÷2=1632 \div 2 = 16.
2
Evaluate the second term: 249+5\frac{2^4}{|-9 + 5|}
4
First, evaluate the expression inside the absolute value brackets: 9+5=4-9 + 5 = -4. The absolute value is 4=4|-4| = 4. Then evaluate the exponent in the numerator: 24=162^4 = 16. Dividing the numerator by the denominator yields 16÷4=416 \div 4 = 4.
3
Subtract the second term from the first term
12
Subtracting the result of the second term from the first term yields 164=1216 - 4 = 12.
