.(I) Find the value of x - (125)⁻³ ÷ (25)¹/⁴ = 5ˣ
Answers
Step-by-step explanation:
25x = 125
meaning: there are “x" times 25 which makes or equals 125.
To know the value of x, we have to subtract or take out 25 from 125 until 125 become 0 , and the number of times 25 is taken out is the value of x.
Or add 25’s until 125 is found. The times you add 25 to get 125 is the value of x.
Using substraction:
First time : take out first “25” from 125;
125–25= 100.
Second time: take out another 25 from the previous result.
100–25= 75.
Third time: take out another 25 from the previous result.
75–25=50
Fourth time: take out another 25 from the previous result i.e. from 50.
50–25=25.
Fifth time: take out another 25 from the previous result.
25–25=0
So from the above five time subtraction,we Can see that five “25” adds up together to make 125 or there are five “25” in 125.
Therefore,x in 25x=125 is 5.
Or simply divide both side by 25
25x = 125
x/25=125/25
x=5
