Answer 1

Given ,

${2}^{x} + {2}^{x} + {2}^{x} = {2}^{9} \\ \\ = > 3 \times {2}^{x} = {2}^{9} \\ \\ = > log(3 \times {2}^{x} ) = log {2}^{9} \\ \\ = > log3 + xlog2 = 9 log2 \\ \\ = > 0.47712 + x \times 0.30103 = 9 \times 0.30103 \\ \\ = > x(0.30103) = 2.70927 - 0.47712 \\ \\ = > 0.30103x = 2.23215 \\ \\ = > x = \frac{2.23215}{0.30103} \\ \\ = > x = 7.415$
