It would be 7/10 because since 10/10 is the Earth, and 3/10 is water, 10-3 is 7.
Step-by-step explanation: ITS RIGHT CAUSE I ACTUALY THOUGHT ABOUT IT
Use the difference of 2 squares (a - b)(a + b) = a^2 - b^2:-
(x - 1/x)(x + 1/x) = x^2 - (1/x)^2
= x^2 - 1/x^2
(x ^2 - 1/x^2)(x^2 + 1 /x^2)
= x^4 - 1/x^4
(x^4 - 1/x^4)(x^4 + 1/x^4)
= x^8 - 1 /x^8 Answer
The answer is 4 because if u divide both equations by eachother you get 4
Answer:
b & d
Step-by-step explanation:
Written out numerically, it is 4x4x4. To work this out you multiply 4x4= 16 and then you have one more 4 to multiply by, so you multiply 16x4=64
