    2.3^x=90 ; i,e 3^x=45 ; x= log45 /log3 ; i,e x= 2+(log5/log3).

    wow! I like your solution. I am a fan of your style. your handwriting is very nice. you made me keep the pen again for a solution! pls keep in touch.

    Was jeder sofort sieht: 3 hoch x = 45 Der Logarithmus ist dann die Lösung (zur Basis 3 von 45)

      Совершенно верно, зачем все эти развороты, повороты?

    6x = 90. X=90/6
    X=15

    Olá professora, só não entendi uma coisa: quando você isolou o X para calcular o logaritimo, só invés de dividir o 45 pelo 3 que ia dar 15, você continuou o cálculo substituindo o 45 pela multiplicação 9 X 5 que é igual a 45. Só que aí na etapa seguinte do cálculo, você resolveu o cálculo como uma adição de frações com o mesmo denominador no caso o 3, mesmo se tratando de uma multiplicação de numeradores que resultava no valor de 45. Gostaria que você me esclarecesse essa dúvida sobre qual a lógica nesse raciocínio, professora?

    You have to indicate the mathematical rules of your calculation in general form . dont just assume every one knows them

    задача не решена-чему же равен x-?
    чистое число?

    Funny I came up with X = 3.463

      it is right !! plug it in and you will get 90

      he also did it without a calculator

    3^x=45
    Xlog3=log45
    X=log45/log3
    =1.6532/0.4771
    =3.4649
    VERIFY
    3^3.4649=?45
    44.9963=❤45✔️

      Or express the answer exactly, it's 2 + log (3, 5)
