82 x 2 = 128
It is 8
8 squared x 2 is equal to 128.
8^2 = 64 The exponent is 2
8^*2) + b^(2) = 18^(2) Algebraically rearranger b^(2) = 18^(2) - 8^(2) Remember two squared terms with a negative (-) between them factors to b^(2) = (18 - 8)( 18 + 8) b^(2) = 10( 26) b^(2) = 260 b = +/- sqrt(260) b = +/- 16.124....
√8 = 2√2 ≈ 2.828
It is 8
2 squared = 4 8 squared = 64 2 squared + 8 squared = 4 + 64 = 68 8 squared - 2 squared = 6 squared = 36 The product of 8 x 2 = 16.
8 squared x 2 is equal to 128.
8 = 4 + 4 = 2² + 2²
Well take (2 squared by 3) that would 2 times 2 which is 4, times 2 which equals 8 so (2 squared by 3) eqauls 8
8^2 = 64 The exponent is 2
2 squared --> 4 2 cubed --> 8 3 squared --> 9 3 cubed --> 27
1 squared plus 8 squared or 4 squared plus 7 squared
8^*2) + b^(2) = 18^(2) Algebraically rearranger b^(2) = 18^(2) - 8^(2) Remember two squared terms with a negative (-) between them factors to b^(2) = (18 - 8)( 18 + 8) b^(2) = 10( 26) b^(2) = 260 b = +/- sqrt(260) b = +/- 16.124....
Square means to multiply by itself. For example, 2 squared=2 x 2=4, or 8 squared=8 x 8=64
2
It is 64.
