16:x::x:25
16/x=x/25
x*x=16*25
xsquare=400
x=root400
x=20
निम्नलिखित में से प्रत्येक समानुपात में x का मान ज्ञात करें :
7 : 4 : : x : 16
Step 1: Simplify and solve using appropriate law of exponents.
Given,
5
3x−1
÷25=125
Since, 25=5×5=5
2
And 125=5×5×5=5
3
Therefore given equation can be written as,
5
3x−1
÷(5)
2
=(5)
3
⇒(5)
3x−1−2
=(5)
3
[∵a
m
÷a
n
=(a)
m−n
]
⇒(5)
3x−3
=(5)
3
On comparing both sides, we get
⇒3x−3=3
⇒3x=6
⇒x=2
Hence, the value of x=2
