1 + 2 x 3-4x 5 + 6 - 7 + 8 x 9 + 10=

Sorry I am really bad at vodkas and stuff please help!

ok this question contains many operations we have addition sign subtraction sign and multiplication sign so in this case we use bodmas and in the bodmas we see multiplication coming fast so the first two letters that have the multiplication sign between them should be multiplied so in this case put a bracket between those two numbers so that you have it like this oneplus (2 x 3)-(4*5) + 6 - 7 plus (8 * 9 )+ 10 so we multiply the numbers in the brackets so that our equation comes to 1 + 6 - 20 + 6 - 7 + 72 + 10 then we rearrange so that you have 1 + 6 plus 6 + 72 + 10 - 20 - 7 1 + 6 + 6 + 72 + 10 is 95 - 20 -7 and your final answer is 68

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)
