Question
Which of the following best describes a computer
virus?Solution
When an infected host file is executed, the virus code runs and may perform harmful actions, such as corrupting data, modifying system settings, or disabling security tools.
Simplify the following expressions and choose the correct option.
{[(13)Β² β (7)Β²] Γ· 12} Γ 4 = ?
(25)Β² Γ 4 Γ· 5 + (3)Β³ + 48=? + 425
?2 + 114 - 48 Γ· 2 Γ 5 = 163
182 + 10 Γ 12 - ? = 312
2/5 of 3/4 of 7/9 of 7200 = ?
If (3 Γ 144 β 252 Γ· 14) Γ· 18 = β1024 β x, then find the value of βxβ.
12.50% of 1440 - 17 × 51 + 721 =?
[(15)³ × (8)²] ÷ (90 × 6) = ?²
?2 - (40% of 240) = 25 X 5
Simplify: 48 Γ· 4 Γ 3 + 5 Γ (6 β 2)
