Solve the equation by factoring.
Delicious77 [7]

Factorizing an expression involves writing the expression in simpler forms

The values of z are z = \frac 15 or z=4

The equation is given as:

5z^2 - 21z + 4 = 0

Expand the equation

5z^2 - 20z -z + 4 = 0

Factorize the expression:

5z(z - 4) -1(z - 4) = 0

Factor out z - 4

(5z - 1)(z - 4) = 0

Split

5z -1 = 0 or z - 4 = 0

Solve for z

z = \frac 15 or z=4

Hence, the values of z are z = \frac 15 or z=4

Apply the laws of exponents, calculate the result and express the result in scientific notation, and as a decimal: (8.1*10^-4)^2
AfilCa [17]
<h3>Answer:</h3>
  • the result in scientific notation is 6.561×10⁻⁷
  • the result as a decimal is 0.000 000 656 1
<h3>Explanation:</h3>

The rules of exponents say the exponent outside parentheses applies to each factor inside parentheses.

... (8.1*10^-4)^2 = 8.1^2 × (10^-4)^2

... = 65.61 × 10^-8

... = 6.561 × 10^-7 . . . . adjust to scientific notation with one digit left of the decimal point

The exponent of -7 means the decimal point in the decimal number is 7 places to the left of where it is in scientific notation. That is ...

... 6.561 × 10^-7 = 0.0000006561
