Note that 8.00 = (2.00)^3, that implies that a decay to 1/8.00 means that the Carbon-14 has passed 3 half-life. (1 to decay to 1/2, other to decay to 1/4, and other to decay to 1/8). And, three half-life is 3 * 5730 years = 17,920 years. So,<span> the answer is that the plant was alive 17,920 years.</span>

To calculate a person’s BMI, you divide their weight( in kg) by their height ( in square meters). First convert 169 pounds to kg, which is 76.66. Then convert 65 inches to meters. 65 inches= 1.65 meters. Then divide 76.66/1.65= 46.46 kg/m

kherson [118]

For this case we must indicate an expression equivalent to:

(3 ^ 6) ^ 3

For properties of powers we have to:

(a ^ n) ^ m = a ^ {n * m}

So, the above expression can be rewritten as:

(3 ^ 6) ^ 3 = 3^{6*3} = 3^{18}

Thus, the resulting expression is: 3^{ 18}

Answer:

3^{ 18}

Option D
