Question

Which is larger?

(1)1001100 (-1)^{100}⬜-1^{100}

Video Solution

Step-by-Step Solution

To determine which is larger between (1)100 (-1)^{100} and 1100-1^{100} , follow these steps:

  • Step 1: Evaluate (1)100 (-1)^{100} .
    Since 100 is an even number, (1)100 (-1)^{100} simplifies to (1)(-1) multiplied by itself 100 times. Even powers of -1 result in 11, so (1)100=1 (-1)^{100} = 1 .
  • Step 2: Evaluate 1100-1^{100} .
    Notice that 1100-1^{100} is simply putting a negative sign in front of 11001^{100}. Since powers of 1 are always 1, 1100=1 1^{100} = 1 , resulting in 1100=1-1^{100} = -1 .
  • Step 3: Compare the results.
    From our calculations, (1)100=1 (-1)^{100} = 1 and 1100=1-1^{100} = -1 . Comparing these, 1>11 > -1.

Thus, the expression (1)100 (-1)^{100} is greater than 1100-1^{100} .

Therefore, the correct comparison is ()100>1100(-)^{100} > -1^{100}.

The correct choice from the possible answers is > > .
