First, we will focus on the exercise with a fraction in the denominator. We will solve it using the formula:
Therefore, we get:
We know that a product raised to the 0 is equal to 1 and therefore:
\( 112^0=\text{?} \)
Dividing by a fraction is the same as multiplying by its reciprocal. So becomes , which simplifies to .
They're exactly the same thing! is just the exponential notation for . Negative exponents always mean 'one over' that base raised to the positive exponent.
Think of it as canceling out: means you have 7 x's on top and 6 x's on bottom. After canceling, you're left with 7 - 6 = 1 x on top, so .
It's much harder that way! Always simplify step by step: first handle , then solve . Breaking it into steps prevents mistakes.
Because we have 1 divided by x, not just x! When you have , that's the definition of . The negative exponent shows we're taking the reciprocal.
