Resolva em R as equações A) 3^2x+1=2187 B)10^x+6=0,001 C)3^x=10 D)e^2x=5

A)
3^(2x+1) = 2187
3^(2x+1) = 3^7
2x+1 = 7
x = 3

B)
10^(x+6) = 0,001
10^(x+6) = 10^-100
x+6 = -100
x = -94

C)
3^x = 10
x = 1 / log3 ou x = 2,0959032742893846042965675220214

D)

e^2x = 5
2x = log5 / loge
2x = 0,69897000433601880478626110527551 / 0,43429448190325182765112891891661
2x = 1,6094379124341003746007593332262
