Simplify the expression if possible 4^3 × 4^5 and write you answer as a power ( using exponents )

alexgriva [62]

Answer:

4^8

Step-by-step explanation:

If you are multiplying two bases that are the same with different exponents, the exponents get added and the base stays the same:

$x^a*x^b=x^{a+b}\\\\4^3*4^5=4^{3+5}\\\\4^3*4^5=4^8$

Therefore, 4^3 * 4^5 = 4^8

K/7 + 3 − 2k = −3<br> Explain how to solve the problem. SHOW YOUR WORK!

Vesna [10]

Answer: 42/13

Step-by-step explanation: Multiply everything by 7 to eliminate the fraction:

k+ 21 - 14k = -21

Isolate the variable:

k - 14k = -21-21

13k= -42

divide the sides by -13.

Given a term in a geometric sequence and the common ratio, find the explicit formula, a11=5120 ans r=-2

sweet-ann [11.9K]

Answer:

$U_n=5(-2)^{n-1}$

Step-by-step explanation:

Given a geometric sequence, the nth term of the geometric sequence is obtained by using the formula:

$U_n=ar^{n-1}$

If the eleventh term, $a_{11}=5120$

and the common ratio, r=-2.

Then:

$5120=a(-2)^{11-1}\\a=\frac{5120}{2^{10}} =5$

The explicit formula for the sequence is:

$U_n=5(-2)^{n-1}$
