Solve for b.
b² = 49
b = ______ or ______
To solve for ( b ) in the equation ( b^2 = 49 ), you need to take the square root of both sides.
1. Start with the equation:
[
b^2 = 49
]
2. Take the square root of both sides:
[
b = pm sqrt{49}
]
3. Since the square root of 49 is 7, you get:
[
b = 7 quad text{or} quad b = -7
]
So, the solutions are ( b = 7 ) or ( b = -7 ).
