Question

Find the value of x. logx 8 = 0.5 А. 4 В. 16 C.32 D. 64

Answer 1

Answer:

The answer to your question is letter D. x = 64

Step-by-step explanation:

Equation

                                       log x 8  = 0.5

Express the log as a exponential equation

                                        x$x^{0.5}$ = 8

Express the power as a fraction

                                        $x^{1/2} = 8$

                                        $\sqrt{x^{2}}$

Look for a number which squared root is 8

                                        $\sqrt{64} = 8$

Then

                                        x = 64
