You're basically looking for the square root of 49. In fact, if a number [tex] x [/tex] gives [tex] y [/tex] when multiplied by itself two times, then you have [tex] x^2 = y [/tex], which also means that [tex] x [/tex] is the square root of [tex] y [/tex], i.e. [tex] x = \sqrt{y} [/tex]
In your case, the answer is 7, because you have
[tex] \sqrt{49}=7 \iff 7^2 = 49 [/tex]
which is indeed true
