Question

11^4x × 11^-3 = 11 ×121^4find x​

Answer 1

Answer:

x = 9/4

Step-by-step explanation:

${11}^{4x} \times { \frac{1}{11} }^{3} = 11 \times {11}^{5} \\ {11}^{4x} = {11}^{5 + 1 } \div \frac{1}{11 {}^{3} } \\ {11}^{4x } = {11}^{6} \times {11}^{3} \\ {11}^{4x} = {11}^{9} \\ by \: comparing \\ 4x = 9 \\ x = \frac{9}{4}$
