Question

b) Find the values of y.
y² = 169
I wrote that it equals to 13 but it’s not right. Please help!!

Answer 1

Answer:

y = ± 13

Step-by-step explanation:

y² = 169 ( take square root of both sides )

y = ± $\sqrt{169}$ = ± 13

since 13 × 13 = 169 and - 13 × - 13 = 169

then y = 13 and y = - 13
