Answer:
Answer with explanation:
The equation is
5 X-2 = 8
Adding 2 on both sides
+5 X-2+2=8+2
+5 x=10
Dividing both sides by,5, we get
+x=2
Using the concept of Logarithms
log b
1. log, b =
=
log a
2. log ab = log a + log b
a
+ log10 5x = log10 10
=
+ log10 5 + log10 X = 1
0.698 + log10 x = 1
log10 X = 1 – 0.698
log x
=
0.302
log 10
log x = (log 100.302)
log 2
=
log 2.044
X =
2.004472
Gives, x=2.005 (Approx
