Question

By the square property, if b is a real number , and a2=b, then a=

Answer 1

Answer:

$a=\sqrt{6},\:a=-\sqrt{6}$

Step-by-step explanation:

Given

• b is a real number

• $a^2=b$

as

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

so

$a^2=6$

$a=\sqrt{b},\:a=-\sqrt{b}$

Therefore,

$a=\sqrt{6},\:a=-\sqrt{6}$
