Question

pls give answer fast​

Answer 1

3 13-7=

3 power 6

3 power 6 / 3 power 7 = 3 power -1

3 power -1 = 3 power 2x-5

x = 2

because 2*2=4

4-5=-1

ans=x=2

Answer 2

${3}^{7} \times {3}^{2x - 5} = {3}^{13} \div {3}^{7} \\ {3}^{2x - 5 + 7} = {3}^{6} \: \\ solving \: exponents \: we \: get \: \\ 2x - 5 + 7= 6 \\ 2x = 12 - 6 \\ 2x = 6 \\ x = 3 \\ {3}^{7} \times {3}^{ - 1} = {3}^{13} \div {3}^{7} \\ {3}^{6} = {3}^{6} \\ hence \: x = 3$
