What is the simplified form of the expression?

A

Step-by-step explanation:

a. type in 2⁻³ in the calculator and you get 0.125, which is 1/8.

b. Anything to the power of 0 will equal 1. :)

A.

Step-by-step explanation:

a.

when you have a negative exponent, the simplified value becomes a fraction:

2^-3

1/2^3

1/8

b.

any number to the power of 0 is equal to one:

(5.5)^0

1

Hope this helps :)

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

the answer is 3/2 and for decimal: 1.5
