What expression is equivalent to 2^-3/2^-5?

1 answer:

6 0

2^2 , or 4
since the exponents have the same base, we can subtract the exponent of the numerator by the exponent in the denominator.

So 2^-3 - 2^-5 = 2^(-3-(-5)) = 2^2

The new exponent is 2 because -3-(-5) is equal to 2.

Step-by-step explanation:

∑ 1 ^30 (3n+1)=4+7+10+... 30 terms

a=4

n=30

d=7-4=3

$S_{30}=\frac{30}{2}[2 \times 4+(30-1) \times 3]\\=15[8+87]\\=15 \times 95\\=1425$

What are the solutions to the equation? x^2+6x = 40.

GaryK [48]

Answer:

x = 4, -10

Step-by-step explanation:

Find the zeros of the equations.

Solve the equation:

x^2 + 6x = 40

Subtract -40 from both sides.

x^2 + 6x - 40 = 0

Factor the equation.

(x - 4)(x + 10)

Solve for x with the given information by equaling it to 0.

x - 4 = 0

Add 4 to both sides

x = 4

x + 10 = 0

Subtract 10 from both sides

x = -10

This means that our x values are:

x = 4, -10
