If you first climb up 3 rungs then down 5 rungs and then up 10 rungs to get onto The top rung how many rungs are on the ladder?
1 answer:
The middle red line is where you're standing at first. Then you go up 3 rungs (the blue lines) and then you go down 5 rungs (look at the yellow arrow and lines) And then you go up 10 rungs (follow the teal arrow up and look at the rungs) count the number of lines above the middle red line and you'll get 8. make sure that there's 8 below the middle red line because the red line has to be in the middle. now count all the lines and you'll get 17.

Answer:
No positive value of n
Step-by-step explanation:
we have to find out for how many positive values of n are both
our-digit integers
Let us consider first cube
we get 4digit lowest number is 1000 and it has cube root as 10.
Thus 10 is the least integer which satisfies four digits for cube.
The highest integer is 9999 and it has cube root as 21.54
or 21 the highest integer.
Considering 3^n we get,
3^10 is having 5 digits and also 3^21
Thus there is no positive value of n which satisfy that both n cube and 3 power n are four digits.
