Question

(7)^6 ÷ (7)^4-x= 7^8​

Answer 1

Answer:

$\frac{ {7}^{6} }{ {7}^{4} - x} = {7}^{8} \\ \\ \\ {7}^{6} = {7}^{8} ( {7}^{4} - x) \\ \\ \\ {7}^{6} = {7}^{8 + 4} - {7}^{8} x \\ \\ \\ {7}^{8} x = {7}^{12} - {7}^{6} \\ \\ \\ x = \frac{ {7}^{12} - {7}^{6} }{ {7}^{8} } \\ \\ \\ x = \frac{ {7}^{12} }{ {7}^{8} } - \frac{ {7}^{6} }{ {7}^{8} } \\ \\ \\ x = {7}^{12 - 8} - {7}^{6 - 8} \\ \\ \\ x = {7}^{4} - {7}^{ - 2} \\ \\ \\ x = {7}^{4} - \frac{1}{ {7}^{2} } \\ \\ \\ x = \frac{ {7}^{4 + 2} - 1}{ {7}^{2} } \\ \\ \\ x = \frac{ {7}^{6} - 1 }{ {7}^{2} } \\ \\ \\ x = 2400.97$
