Answer:
Step-by-step explanation:
40a²b = 2* 2 * 2 * 5 * a² * b = 2³ * 5 * a² * b
48ab⁴ = 2 * 2 * 2 * 2 * 3 * a *b⁴ = 2⁴ * 3 * a * b⁴
LCM = 2⁴ * 3 * 5 * a² * b⁴
= 16 * 3 * 5 * a² * b⁴
= 240a²b⁴
The answer to the question
Answer:
-cos(x)
Step-by-step explanation:
y¹ = cos(x)
y² = -sin(x)
y³ = -cos(x)
y⁴ = sin(x)
Every 4th derivative is sin(x)
123 = 4(30) + 3
y¹²⁰ = sin(x)
y¹²¹ = cos(x)
y¹²² = -sin(x)
y¹²³ = -cos(x)
Rounded to the nearest ten thousand it would be 50,000
Take the 4 and 30/60 which is equal to 4.5 or 4 1/2 and add 1 1/4. make the 1/2 a common denominator by multiplying the top and bottom by 2 to give you 2/4. add the 4 2/4 to the 1 1/4 to give you the final answer of 5 3/4
