\\ \tt\hookrightarrow 2(3)^{12t}=1200

  • Isolate the term

\\ \tt\hookrightarrow (3)^{12t}=600

  • Apply log on both sides

\\ \tt\hookrightarrow log(3)^{12t}=log600

\boxed{\sf log_a b=bloga}

\\ \tt\hookrightarrow 12tlog3=log600

\\ \tt\hookrightarrow t=\dfrac{log600}{12log3}

\\ \tt\hookrightarrow t=\dfrac{2.778}{12(0.477)}

\\ \tt\hookrightarrow t=\dfrac{2.778}{5.724}

\\ \tt\hookrightarrow t=0.485

What is the second step when evaluating the expression 49 + 63 ÷ (3 + 2 × 2) – 7? 63 ÷ 3 63 ÷ 7 2 × 2 3 + 4
Zarrin [17]

ANSWER: Multiply and Divide from left to right

To do this question we must follow the rules of PEMDAS. The first step would be to evaluate the equation given to us in the parentheses. To solve that we would have to use PEMDAS once again which tells us to multiply 2 x 2 before we add 3, so we get 7. Now that there is no more Parentheses, our second step is to evaluate each Multiplication and Division expression from left to right. This would start by dividing 63 by 7 to get 9.
