Q. Which expression is equivalent to 4−3(43)0?04−3143
Simplify numerator: Simplify the numerator ((43)0). Any number raised to the power of 0 is 1. Therefore, ((43)0)=1.
Simplify denominator: Simplify the denominator 4−3. A negative exponent means that the base is on the wrong side of the fraction line, so we take the reciprocal of the base and make the exponent positive. Therefore, 4−3=431.
Write expression: Write the expression after simplifying the numerator and the denominator.We have 1 for the numerator from Step 1 and 1/(43) for the denominator from Step 2.So, the expression becomes 1/(1/(43)).
Simplify final expression: Simplify the expression 1/(1/(43)). When dividing by a fraction, it is equivalent to multiplying by its reciprocal. Therefore, 1/(1/(43))=1×(43)=43.
