Question

If the question is then what will be the answer2^5=8^x then x=

Answer 1

Solution:

Given,

2⁵ = 8^x

We know that 8 can be written as 2³

Substituting we have

2⁵ = 2^(3x)

Using aⁿ = a^m → m = n

Similarly

5 = 3x

x = 5/3

Hence , x = 5/3

Some important formulas

a^n - a^m = a^n/a^m

a^n × a^m = a^(m + n)

(a + b)² = a² + b² + 2ab

(a - b)² = a² + b² - 2ab

Note : ^ ← this symbol indicates power
