If = (32)−2÷ (67)0, find the value of ()−3. Express the value in exponential form with positive exponent.

Example

Problem

Evaluate.

5x3 if x = 4

5 • 43

Substitute 4 for the variable x.

5(4 • 4 • 4) = 5 • 64

Evaluate 43.

320

Multiply.

Answer

5x3 = 320 when x = 4

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
