8.333333
let x=8.33333 and 10x=83.33333
10x-x=83.333-8.333
9x=75
x=75/9
x=25/3
x=8 1/3
Now if you meant:
8.383838 then
100x-x=838.3838-8.3838
99x=830
x=830/99
Answer:
Step-by-step explanation:
C11 = (1×1) + (-1×3) = 1-3 = -2
C12 = (1×2) + (-1×4) = 2-4 = -2
C21 = (2×1) + (1×3) = 2+3 = 5
C22 = (2×2) + (1×4) = 4+4 = 8
Answer:
3x^2(x+5)
Step-by-step explanation:
Answer:
The correct option is:
1/81
Step-by-step explanation:
The given expression to us is:
(3²)⁻²
In this expression, the two powers, which are 2 and -2, are multiplying with each other, we can write it as:
(3)⁻⁴
Now we know that a negative power of a number can be converted into a positive power one if we take reciprocal of the given number.
It can be written as:
(1/3)⁴
Further simplify the expression:
1/81
Thus the correct choice from the given options is:
1 over 81 or 1/81
Cos (90-x) x is 28. I hope this helps you.
