Question

A natural number is grearer than 3 times
its square root by 4. find the number..​

Answer 1

Answer:

the number is 16

let the unknown no be n

the equation becomes

n-3(n)^1/2=4

now let n= x^2

by soving the quadratic we get n=1 or 4

n=1 is rejected as it does not satisfies th given equation

now n=4

thus x=16

so the answe we are looking for is 16 as it satisfies the equation

16-3*4=4
