I'm unable to write the problem like it is on my worksheet. What should I do?

Use an up arrow ^ to indicate a superscript. So 45 squared would be written as 5^2, 5 cubed would be 5^3, and 5 to the 20th power would be 5^20. Use an asterisk * to indicate multiplication and a forward slash / to indicate division. Use parentheses to group numbers.If you intended to write 3^4 * 3^2 then this would be solved as follows:3^4 = 3*3*3*3 = 813^2 = 3*3 = 93^4 * 3^2 = 81 * 9 = 729
