Answer:
1. Read through the problem and figure out what it's about.
Represent numbers you don't know with variables.
Translate the problem into a mathematical expression.
Solve the problem.
Check your work.
Step-by-step explanation:
<span>3 = log(8) + log(x³) </span>
<span>When adding logs, you are multiplying the terms altogether. </span>
<span>3 = log(8x³) </span>
<span>Then, by log_a b = n ==> aⁿ = b: </span>
<span>10³ = 8x³ [Since the base is not given, I assume that the base is 10] </span>
<span>1000 = 8x³ </span>
<span>Finally, solve for x. </span>
<span>1000/8 = x³ </span>
<span>x³ = 125 </span>
<span>x = (125)^(1/3) . . .Set both sides to the power of 1/3. </span>
<span>x = 5 </span>
<span>Hence, x = 5. </span>
This would be 50 rounded to the nearest ten
Answer:
15%
If you get 7.5 from 75 by moving over 1 decimal place then divide 112.50 by 7.5 you get 15 percent as your answer
So b=-2 so you plug b in
l(-2)l + (-2)^3.
The absolute value of -2 is just 2 so now it is
2 + (-2)^3.
-2 * -2 is 4 but 4 * -2 is -8. So 2 + (-8) or 2 - 8 which comes to equal (-6) or negative six.
