Q. Which expression is equivalent to (505−1)−3?2512501251
Simplify base: Simplify the base of the expression.We have the expression ((5−1)/(50))−3. First, we need to simplify the base (5−1)/(50).Since any number to the power of 0 is 1, we have 50=1.So, the base simplifies to 5−1/1, which is just 5−1.
Apply negative exponent: Apply the negative exponent to the base.Now we have (5−1)−3. When we raise a power to a power, we multiply the exponents.So, (−1)×(−3)=3.Therefore, the expression simplifies to 53.
Calculate value: Calculate the value of 53. 53 means 5 multiplied by itself 3 times. So, 5×5×5=125.
