Question

Qual o valor de 3 elevado a x = 4

Answer 1

3ⁿ= 4

Log3ⁿ= Log 2²
n*Log3= 2 Log2

Log 3= 0,477
Log 2= 0,301

n*0,477= 2*0,301
0,477x= 0,602
n= 0,602/0,477
n= 1,262

Forte abraço!

Answer 2

3^x = 4

Log 3^x = Log 2^2
x Log 3 = 2 Log 2 
x * 0,477 = 2 * 0,301
0,477 x = 0,602
x = 0,602 / 0,477
x = 1,262
