Your answer :
the 2nd power of 1  = 1  3 raised to the 2nd power  = 9 23  = 8 52  = 25  This group contains a mistake.
Well, let’s see:
the 2nd power of 1  = 12 = 1 × 1 = 1;  3 raised to the 2nd power  = 32 = 3 × 3 = 9; 23  = 2 × 2 × 2 = 8; 52  = 5 × 5 = 25.
They’re all correct. Return to Page 15 and try again.
