Step-by-step Solution
To solve for \( d \) when \( d^2 = 9 \), you need to find the square roots of 9. The square root of a number is a value that, when multiplied by itself, gives the original number. Since 9 is a perfect square (3 times 3), it has two square roots: one positive and one negative.
The positive square root of 9 is 3, because \( 3 \times 3 = 9 \).
The negative square root of 9 is -3, because \( -3 \times -3 = 9 \).
Therefore, \( d \) can have two values: 3 and -3.
Quick Answer
\( d \) can be 3 or -3.
