Question

Find the value x = 1/(sqrt(40 * 10 ^ - 15))​

Answer 1

Concept

Expression means a combination of numbers, symbols and variables in equal to form. It is often used to calculate the variables and evaluate the expression.

Given

Expression: x=$1/\sqrt{(40*10^{-15} }$

Find

The value of expression  x=$1/\sqrt{(40*10^{-15} }$

Explanation

We have to find the value of expression x=$1/\sqrt{(40*10^{-15} }$ and to solve this we have to solve the expression with the help of log.

Take log both sides

log x=log($1/\sqrt{(40*10^{-15} }$)

log x=log 1-log $\sqrt{40*10^{-15} }$

log x=log1-(log 40+log $10^{-15}$)/2

log x=log 1 -(log 40-15log 10)/2

log x=log1 -log40/2+15log 10/2

log x =0-1.60205999/2+15/2*1

log x=6.69897005

x= Antilog(6.69897005)

x=5000000

Hence the value of x is 5000000 approx.

Answer 2

Answer:

X = 5000000

Step-by-step explanation:

     TO FIND:

                   X value.

GIVEN:

       $x=\frac{1}{\sqrt{40*10^{-15} } }$

       $x=\frac{1}{0.0000002}$

      $x=5000000$
