Best ResponseYou've already chosen the best response.0\[169 = \sqrt{177+b ^{2}}\]

Best ResponseYou've already chosen the best response.0square both sides to find \[28561=177+b ^{2}\]

Best ResponseYou've already chosen the best response.0subtract 177 from both sides: 28394=b^2

Best ResponseYou've already chosen the best response.0take the square root of both sides to solve for b \[\sqrt{28384} = b = 168.476\] (approximately)

Best ResponseYou've already chosen the best response.0oh so i don't square root the 177 til the end???

Best ResponseYou've already chosen the best response.0was the original problem \[13^{2}=\sqrt{177+b ^{2}}\]?

Best ResponseYou've already chosen the best response.0We never had to find the square root of 177 by itself

Best ResponseYou've already chosen the best response.0If you square a square root, the square root goes away. That's what I did to find 28561=177+b^2

Best ResponseYou've already chosen the best response.0from there I subtracted 177 from both sides to get the variable by itself

Best ResponseYou've already chosen the best response.0so then the equation becomes \[28384 = b ^{2}\]

anonymous

Best ResponseYou've already chosen the best response.0then to solve for b, i took the square root of both sides
