Answer:

Step-by-step explanation

Factoring: 2x3-5x2+7x-6

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: 7x-6

Group 2: 2x3-5x2

so its c

Pull out from each group separately :

Group 1: (7x-6) • (1)

Group 2: (2x-5) • (x2)

Bad news !! Factoring by pulling out fails :

The groups have no common factor and can not be added up to form a multiplication.

For exponential functions which of the following expression is equal to [f(3)]^4]

Molodets [167]

Answer:

$F(3*4)$

Step-by-step explanation:

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