Important Definition for RS Aggarwal Class 8 Maths Chapter 2 Ex 2.1 Solutions
- Negative exponent
A negative exponent is a base that is on the wrong side of the fraction line. The students need to flip the base to the other side.
For example, x–2 means x2, but underneath, as in 1/x2.
Each negative exponent can be expressed as a positive reciprocal. A reciprocal is a fraction where the numerator & denominator change places.
- A negative number is any number less than zero.
Negative numbers are expressed with a negative sign.
For instance: -4 is four less than zero. If the students add & subtract negative numbers, they either move to the right or the left of the number line.
When they subtract a negative number they move to the left of the number line as it’s the same as adding a positive number. If they add a negative number, they move to the right because it’s the same as subtracting a positive number.
- How to solve negative fraction exponents
When the students multiply a negative number by a positive number or vice versa, the number will be negative. If they multiply two positive numbers or two negative numbers, the result will be positive.
- Some Rules need to follow:
- If multiplying like bases, add powers together
- If dividing like bases, subtract powers
- If raising power by another exponent, multiply powers together
- If raising several variables by a power, distribute power to each base
- If raising several variables by a power, distribute power to each base
- Any base raised to the power of zero becomes 1
- If changing a negative exponent to a positive one, flip it into a reciprocal.
