<u>what is a power rule for exponents ?</u>

(a^m)^n=a^{mn} is known as the power rule for exponents. Exponent times power is how you raise a number with an exponent to a power.

A number's exponent demonstrates how many times we are multiplying a given number by itself. 3^4, for instance, indicates that we are multiplying 3 by four. 3*3*3*3 is its expanded form. The power of a number is another name for an exponent. It could be an integer, a fraction, a negative integer, or a decimal.

(7^{\frac{1}{3}})^{3} = (7^{\frac{1}{3}*3}) = 7^1=7

Here, we have used the rule (a^m)^n=a^{mn}

Which is an equation of the line whose
Montano1993 [528]

Answer:

y = 2x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, so

y = 2x + c ← is the partial equation

To find c substitute (- 2, 3 ) into the partial equation

3 = - 4 + c ⇒ c = 3 + 4 = 7

y = 2x + 7 ← equation of line
