Correct each of the following errors by circling the error, describing what is wrong, entering what should be there instead, and entering the correct answer. (3x^{2})t(-2x^{4})=3(-2)x^{2*4}=6x^ {8}

4a^{2} * 3a^{5} = (4 + 3)a^{2+5} = 7a^{7}

x^{6} * x * x^{3} = x^{6+3} = x^{9}

3^{4} * 2^{3} = 6^{4+3}

I need this ASAP pls do soon
