Solve the equation. If necessary, round to the nearest thousandth.2e4x – 3 = 8

Write in logarithmic form.41/2 = 2

Approximate the number using a calculator. Round your answer to three decimal places.5-1.9

Find the product. Write the answer in standard form.(-1 + 7i)(-1 – 7i)

Find the sum or difference. Write the answer in standard form.(-5 + 4i) – (5 + 7i) + (4 – 9i)

 = 5 – 2x

Solve each equation.x2 – 14x + 74 = 0

Evaluate or simplify the expression without using a calculator.log 

Determine whether the equation has a graph that is symmetric with respect to the y-axis, the x-axis, the origin, or none of these.x2 – y2 = 7

What will the following code output if the variable score is set to 75? if (marks >= 90) {    System.out.println(“A”);} else if (marks >= 80) {    if (marks > 85 && marks < 90) {        System.out.println("B+");    } else {        System.out.println("B");    }} else if (marks >= 70) {    if (marks >= 75) {        System.out.println(“C+”);    } else {        System.out.println(“C”);    }} else {    System.out.println(“D or lower”);}
