Question

spiral review 4 - grade in sis
which of the following has a square root of -18 and 18?
334
324
314
304

Explanation:

Step1: Recall square root definition

If a number \( x \) has square roots \( a \) and \( -a \), then \( x = a^2 \). Here, \( a = 18 \), so we calculate \( 18^2 \).

Step2: Calculate \( 18^2 \)

\( 18\times18 = 324 \). So we check which option is 324.

Answer:

B. 324 (assuming the options are labeled as A. 334, B. 324, C. 314, D. 304)
