4 squared means multiplied by itself so 2 squared is 2 times 2 which is 4 if i took 7 squared, that would be 7 times 7 which is 49
(8w + 7)(8w - 7)
7 metres squared = 8.372 sq yards.
No, not strictly speaking. Length squared would have the same units as area but is not equal to it. Length x width is area. If I have a rectangle that is 4m wide x 7m in length then the area would be 7x4 = 28 m2. But length squared would be 7 x 7 = 49m2 which is incorrect.
7 squared is 49 and 5 squared is 25. So the difference is 49-25=24
-7 squared, which would be -49.
4 squared means multiplied by itself so 2 squared is 2 times 2 which is 4 if i took 7 squared, that would be 7 times 7 which is 49
7 to the power of 5 squared would be written (75)2 Working the brackets first, you would take 7 to the power of 5, which is 7x7x7x7x7, giving 16,807 16,807 is then squared, and 16,807x16,807 = 282,475,249 so that would be your answer.
7(squared) or 7(sq)
(8w + 7)(8w - 7)

Seven squared = 7 x 7 = 49
