X²=169 extracting square root

x = ± 13

Step-by-step explanation:

Given

x² = 169 ( take the square root of both sides )

x = ± = ± 13

Since 13 × 13 = 169 and - 13× - 13 = 169

step-by-step explanation:

in 2010, the population of the state of california is 37.29 × 10⁶

step-by-step explanation:

population of los angeles = 3.79 × 10⁶

population of california = 9.84 × population of los angeles

                                        = 9.84 × 3.79 × 10⁶

                                        = 37.2936 × 10⁶

                                        = 37.29 × 10⁶

∴ in 2010, the population of the state of california is 37.29 × 10⁶
