Simple, use PEMDAS and then do your simple math and then your answer should be 86922.56604
I believe the percentage is 33% of all kids i added all numbers table is a bit confusing
As they are similar corresponding sides are in the same ratio, so
18/15 = x / 4
x = 4*18 / 15
x = 4.8 answer
4^3= 64
2^6= 64
Therefore, n=6.
You can also figure this out if you know that 2^3*2^6=2^9. When you multiply exponents with the same base, add the exponents. 3+6=9
Final answer: n=6
