Tina's bakery sells cinnamon, banana ,apple ,blueberry muffins. Each day, the bakery bakes 63 apple muffins. The apple muffins represent 42% of all muffins baked each day. How many muffins are baked each day

150 in a day.

Step-by-step explanation:

We need to find the equivalent of 100% to get the total number made in a day:

42%  =  63  

1% = 63/42

100% = (63/42) * 100

= 3/2 * 100

= 150.

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:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
