1.5x1.5=2.25
2.25
It can be broken down into:
(1 + 0.5)² = (1 + 0.5)(1 + 0.5) = 1² + 1 x 0.5 + 0.5 x 1 + 0.5² = 1 + 0.5 + 0.5 + 0.25 = 2.25
Alternatively, using fractions:
1.5 = 1 1/2 = 3/2
→ 1.5² = (3/2)² = (3²)/(2²) = 9/4 = 2 1/4 = 2.25
-15 squared is equal to -15 x -15. Since multiplying two negative numbers together gives a positive number, this is the same as multiplying together 15 and 15.
Therefore, -15 x -15, or -152 = 152 = 225.
the answer to 15 squared is 225
