3.8 Mocha intends to go and reside at Marble
Hall (a residential area) from his current
home in Ga-Masemola (a communal stand).
He will continue with
gardening at his new
residence and will restrict the water usage to
the usual 32 kl a month.
2.8.1 Calculate the cost of using 32 kl of water a month at Ga-Masemola (a
communal piped area) using a pre-paid option.
8.35lX 32
(2)

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

step-by-step explanation:

answer: f = 32.2m

step-by-step explanation: that is the answer

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
