Question

(519)-2/9.find the value​

Answer 1

Answer:

2531-2519=x

Step by Step solution

Rewrite using the law of exponents

Using the law that xmxn = xm+n we can rewrite:

2531 as 2(519+12)

and

2519 as 2(519+0)

And then,

2(519+12) as 2519×212

and

2(519+0) as 2519×20 to end up with

2519×212 - 2519×20=x

Pull Out like Terms

At this time, we also replace 20 with 1 as per the law of exponents that x0=1

2519(212-1)=x

2^12=2×2×2×2×2×2×2×2×2×2×2×2×2=4096

2519(4096-1)=x

4095×2519=x

Final Result

4095×2519=x

Theory

Laws of exponents

x1 = x

x0 = 1

x-1= 1 / x

xmxn = xm+n

2-1=0.5

20=1

21=2

22=4

23=8

24=16

25=32
