What are the errors in this equation and what is the correct answer

3^4 • 2^3 = 6^4+3 = 6^7​​

3x2−7x−6=0

x=−7±(−7)2−4(3)(−6)√2(3) =−7±121√6 x=23 and x=−3 x = − 7 ± ( − 7 ) 2 − 4 ( 3 ) ( − 6 ) 2 ( 3 )   = − 7 ± 121 6   x = 2 3  and  x = − 3    

Step-by-step explanation:

648

Step-by-step explanation:

bases of 3 and 2 are not the same so cannot multiply them and add exponents

3^4 = 81

2^3 = 8

81 x 8 = 648
