Step-by-step explanation:
_1.5 because it is betwwen the _1 and _2
8x^3 + 1 = 0
8x^3 = -1 <----------- Step 1: Subtract 1 from both sides.
x^3 = -1/8 <----------- Step 2: Divide both sides by 8.
x = ∛(-1/8) <----------- Step 3: Cube root both sides
x = -0.5 <----------- This is the final answer when you plug the last step into the calculator
Expanded form: 720,080 = 700,000 + 20,000 + 80
To write in exponential form, it's easier to write it out.
700,000 + 20,000 + 80.
7<u>00</u>,<u>000</u> = 7 x 10^<u>5</u> (the exponent equals how many zeros there are.)
20,000 = 2 x 10^4 (There are 4 zeros so the exponent is 4)
80 = 8 x 10^1 (There are 1 zero so the exponent is 1)
Exponential form: (7 x 10^5) + (2 x 10^4) + (8 x 10^1)
