Question
Find the value of ( 8-25 - 8-26 )
Hint:
In Mathematics, lets say, "a" represents a number and "n" is the number of times that number is to be multiplied with itself, in order to get a desired result. Then, such result can be written as an, where a is called the base and n is its power/ exponent.
an = a × a × ... × a n times.
The correct answer is: value of the given expression, when simplified is 7/826.
Step-by-step solution:-
(8-25 - 8-26)
∴ 1/825 - 1/826 …....................................... (b-n = 1/bn)
∴ 8/826 - 1/826 …..................................... (Multiplying & Dividing the first expression with 8 to make the denominators equal)
∴ 8-1 / 826
∴ 7/826
Final Answer:-
∴ value of the given expression, when simplified is 7/826.
