No. 7 to 10 are simple. Find the square root meaning, for example, 3^2 or 3×3 = 9 so the answer to no. 7 is 3, no.8 is 8, no. 9 is 2 and no. 10 is 12.
From nos. 11 to 14 find the root like no. 11 is 11 because 11^2 or 11 × 11 = 121. However, 12, 13, and 14 should indicate the signs because there might be two solutions. Once you go to higher maths they might require signs because it requires two solutions. In no. 12 it is 14 or -14. No, 13 is 5/8 or -5/8 and 14 no clue.
