\huge{\boxed{227}}

Here's our expression: 3*(5+4)^{2}-4^{2}

We will follow the order of operations and begin by solving everything in parentheses. 3*9^{2}-4^{2}

Next, we solve the exponents. 3*81-16

Now, we solve the multiplication and division. There is no division, so we will just solve the multiplication. 243-16

Finally, we solve the addition and subtraction. Since there is no addition, we will solve the subtraction. \boxed{227}

Solve this equation for x. Round your answer to the nearest hundredth. 0.77 = log x​
Alekssandra [29.7K]

Answer:

x ≈ 5.89

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra II</u>

  • Exponential to Logarithmic:                                                                             \displaystyle b^m=x \rightarrow log_bx=m

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

0.77 = log(x)

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. [Equality Property] Raise both sides to the 10th power:                                \displaysytle 10^{0.77} = 10^{logx}
  2. Simplify:                                                                                                             \displaysytle x = 10^{0.77}
  3. Evaluate:                                                                                                           \displaysytle x = 5.88844
