Select all the pairs of equivalent expressions.

iren2701 [21]

Answer:

$\huge\boxed{(3^4)^4=3^8\cdot3^8}\\\boxed{4^3\cdot5^3=20^3}\\\boxed{(4^3)^3=4^3\cdot4^3\cdo4^3}$

Step-by-step explanation:

$a^n\cdot a^n=a^{n+m}\\\\(a^n)^m=a^{n\cdot m}\\\\(a\cdot b)^n=a^n\cdot b^n\\=====================$

$(4^3)^3=4^{3\cdot3}=4^9\\4^3\cdot4^3=4^{3+3}=4^6\\\\4^9\neq4^6\to(4^3)^3\neq4^3\cdot4^3\\==================$

$(3^4)^4=3^{4\cdot4}=3^{16}\\3^8\cdot3^8=3^{8+8}=3^{16}\\\\(3^4)^4=3^8\cdot3^8\\================$

$6^4\cdot3^4=(6\cdot3)^4=18^4\\\\18^4\neq18^8\to6^4\cdot3^4\neq18^8\\=================$

$4^3\cdot5^3=(4\cdot5)^3=20^3\\\\4^3\cdot5^3=20^3\\=================$

$(4^3)^3=4^{3\cdot3}=4^9\\4^3\cdot4^3\cdot4^3=4^{3+3+3}=4^9\\\\(4^3)^3=4^3\cdot4^3\cdot4^3$

The formula

son4ous [18]

Answer:

The truck travel must to have a constant speed of $22.06\ ft/sec$

Step-by-step explanation:

we have

$d=1.3t^{2}+t+2$

where

d expresses a car's distance in feet

t is the number of seconds

Find the distance d for t=8 sec

$d=1.3(8)^{2}+8+2=93.2\ ft$

Find the distance d for t=8.2 sec

$d=1.3(8.2)^{2}+8.2+2=97.612\ ft$

The total distance in this interval of 0.2 sec is

$97.612-93.2=4.412\ ft$

Find the speed of the car

Divide the total distance by the time

$4.412/0.2=22.06\ ft/sec$

therefore

The truck travel must to have a constant speed of $22.06\ ft/sec$

What is A number divided by 82

lara [203]

Answer:

Hey there, Lets solve this step by step.

A number t divided by 82

Let the number be represented by y.

t divided by 82 = t / 8

Therefore-

In algebraic expressions, "y" is normally used as the dependent variable and "x" is normally used as the independent variable, instead of other variables. So that is why i used the variable y in the equation.
