Answer: D. 6.5 g

Step-by-step explanation:

From the given table , weight of sample 1 = 1.25050 g

Weight of sample 2 = 2.50055 g

Weight of sample 1 = 2.74099 g

The total weight of all the 3 samples= $1.25050\ g+2.50055\ g+2.74099\ g$

Therefore, the total weight of all the 3 samples= $6.49204\ g$

Since, $6.49204\approx6.5$

Thus, the estimated total weight of all 3 samples= 6.5 g

Answer:

$F(3*4)$

Step-by-step explanation:

$Let\ exponential\ function\ F(x)=a^x\\\\F(3)=a^3\\\\\{F(3)\}^4=\{a^3\}^4\\\\\{F(3)\}^4=a^{3\times 4}...........eq(1)\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ as\ (m^n)^k=m^{nk}\\\\Now\ F(3*4)=a^{3\times 4}.......eq(2)\\\\From\ eq1\ and\ eq2\\\\\{F(3)\}^4=F(3\times 4)\\\\\{F(3)\}^4=F(3*4)$
