0.3 в степени х =корень в 4степени под корнем 0.0081 помогите решить

Answer 1

Оооох уж эти корни корень 4 степени из(0.0016*81)корень 4 степени из(0.04^2*3^4)(0.04^2*3^4)^(1/4)=0.04^0.5*3=0.2*3=0.6 Куб корень из(64*0.001)4*0.1=0.4 корень 4 степени из(0.0081*16)(0.09^2*4^2)^(1/4)=0.09^(1/2)*4^(1/2)=0.3*2=0.6

Answer 2

Solving the Equation 0.3^x = √(0.0081)

To solve the equation 0.3^x = √(0.0081), we can use logarithms to isolate the variable x.

First, let's express √(0.0081) as a power of 0.3: √(0.0081) = 0.3^(1/2) * 0.3^(2) = 0.3^(2.5)

Now, we can rewrite the equation as: 0.3^x = 0.3^(2.5)

By equating the exponents, we get: x = 2.5

So, x = 2.5 is the solution to the equation 0.3^x = √(0.0081).

This solution is obtained by equating the exponents of 0.3 on both sides of the equation
