Answer:
Step-by-step explanation:
Let n represent the number
Twice the number =2n
4 times the number = 4n
Given that twice the number is atleast 3 less than four times the number
Algebraically this can be written as
2n≤4n-3
We can add 3 to both sides
So n should be atleast 1.5
If n is natural number or integer then least value of n is 2.
Answer:
x₁ = -3√2 , x₂ = 3√2
Step-by-step explanation:
x² = 18 ⇔ x = √18 or x= -√18
√18 = √[9•2] = √9•√2 = 3•√2 = 3√2
