Question

(1) A natural number is greater than three times its square root
by 4. Find the number. Check your answer​

Answer 1

Answer:

let the number be'x'

x-4=3√x

squaring on both sides,

x²+16-8x=9x

x²-17x+16=0

x²-16x-1x+16=0

x(x-16)-1(x-16)=0

(x-1)(x-16)=0

therefore, the number is 1 or 16
