What is the largest number of real roots that a 7th degree polynomial could have? What is the smallest? |
A seventh degree polynomial has at least one and at most 7 real roots. |
solve: (1 + 6 − 8 − 32 + 3)
-7
Multiply 104 by 102
C: When multiplying terms with the same base, the exponents should be added. Thus, 104 . 102=106.
-(-x - 5) + 5(x - 9) = 2(x + 8) -(2x + 5)

Divide x5 by x2
D: When dividing terms with the same base, the exponents should be subtracted. Thus, x5/x2 =x3.

83,000 equals:
B: Moving the decimal to the right of the digit, 8, gives the equivalent expression, 8.3x104, since there are 4 digits to the right of the 8.
