Q. Solve for x, rounding to the nearest hundredth.29⋅105x=203Answer:
Isolate variable x: First, we need to isolate the term with the variable x. To do this, we divide both sides of the equation by 29.2929⋅10(x/5)=29203
Calculate right side: After dividing both sides by 29, we get:10(x/5)=29203Now we can calculate the right side of the equation.10(x/5)≈7.00
Take natural logarithm: Next, we need to solve for x. To do this, we take the natural logarithm (ln) of both sides of the equation to remove the exponent on the left side.ln(10(x/5))=ln(7.00)
Simplify left side: Using the property of logarithms that ln(ab)=b⋅ln(a), we can simplify the left side of the equation:5x⋅ln(10)=ln(7.00)
Solve for x: Now we can solve for x by multiplying both sides of the equation by 5 and then dividing by ln(10):x=ln(10)5⋅ln(7.00)
Calculate x value: Finally, we calculate the value of x using a calculator:x≈ln(10)5⋅ln(7.00)≈2.302595⋅1.94591≈4.23
