What is the value of begin expression . . 81 times x raised to the second power, times y raised to the third power, plus z . . end exression, if x equals 3, y equals 4, and z equals 19?

46,675

Step-by-step explanation:

So the given expression can be written as:

(81x^2 * y^3 + z)

Given: x=3, y=4, z=19

we have to put each value in the equation above

=>  (81(3)^2 * 4^3 + 19)

Among the 'power', 'multiplication' and 'addition', power has the highest priority, so:

=> (81*9 * 64 + 19)

Multiplication has the second highest priority,

=> (729*64+19)

=> (46,656+19)

=> (46,675)

40 is the final : )

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
