1 9th = 2 18ths
If you don't know what x is then there is nothing more you can do with that problem. At least in 9th grade algebra haha.
I am a plus 2 student..... in 9th standard the escape velocity of a rocket to go to outside the earth is 11.13km/sec not sure .13 or not
1000 to the 9th power, written as (1000^9), equals (10^{27}) or 1 followed by 27 zeros. This is because (1000) is (10^3), and raising it to the 9th power results in (10^{3 \times 9} = 10^{27}). Therefore, (1000^9 = 1,000,000,000,000,000,000,000,000,000).
The 9th multiple of 2 can be calculated by multiplying 2 by 9, which equals 18. In mathematical terms, the formula to find the nth multiple of a number is given by n * x, where n is the position of the multiple and x is the number being multiplied. Therefore, the 9th multiple of 2 is 18.
