Answer:
13
Step-by-step explanation:
W^2 - 63 = 106
W^2 = 106 + 63
W^2 = 169
W = √169
W = 13
The solution of [tex]w^{2}-63=106[/tex] is 13
Solution:
Given equation is [tex]w^{2}-63=106[/tex]
Let us solve the given equation
When we move a number from L.H.S to R. H.S or vice – versa, there sign changes from negative to positive; division to multiplication; positive to negative; multiplication to division
[tex]\mathrm{w}^{2}=106+63[/tex]
Add the terms in right side
[tex]\mathrm{Now}, \mathrm{w}^{2}=169[/tex]
Taking square root on both sides, we get
[tex]w=\sqrt{169}[/tex]
[tex]\begin{array}{l}{w=\sqrt{13 \times 13}} \\\\ {w=13}\end{array}[/tex]
Hence the value of given equation is 13
