Use the properties of powers. In this case, you can combine powers with the same base, by simply adding the exponents.
its 19 X15/100 = 2.85
18
The x-15 can fly at 4520 mph
80,790 gallons
36 x15 180 360 540
28 x15 140 280 420
If 15 cm is the diameter then circumference is pie x diameter which is 3.14 x15
11.25 75% of 15 = (75/100)x15=11.24
first you find 15% of 800. 800/100 is 8, x15 = 120. 800-120 is 680
54/100, x15 is 8.10. 54-8.10 is 45.90
It is 4 times 15 = 60 square feet
It is √(x15), which can be simplified to approx 3.873*√x.
