Answer: 4.13 x 10^4
Step-by-step explanation: You have to just count the places such as the tens all the way to the thousands which leaves you with the exponent of 4.
0.600 = six thousandths written out
150%. since you already have 6, that's 100%. the extra 3 is half of the 6, meaning that it would be 50%
Not quite sure what you mean by brackets, but you can get the solution to this equation in a few steps:
<span>(-2x - 1)</span>² <span>= 0 ... square root both sides to eliminate the squared binomial
</span>√(-2x - 1)² = √0 ... simplify; the square is canceled out and the root of 0 brings you back to 0
-2x - 1 = 0 ... solve like a two-step equation
-2x = 1
x = -1/2 is your x-value.
