Answer:
17
Step-by-step explanation:
8.5 / 0.5
We are given the following conversion factor:

We are asked to determine how many miles are 140 km. To do that we use the quotient of the conversion factor where the unit we want to convert to is in the numerator and the given unit in the denominator. Since we want to find miles we use the following quotient:

Solving the operations we get:
3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679821480865132823066470938 etc.
Answer: =34
=3⋅3⋅3⋅3
=81
For example, 3 to the power of -4:
=3−4
=134
=13⋅3⋅3⋅3
=181
=0.012346
Step-by-step explanation: the solution is expanded when the base x and exponent n are small enough to fit on the screen. Generally, this feature is available when base x is a positive or negative single digit integer raised to the power of a positive or negative single digit integer. Also, when base x is a positive or negative two digit integer raised to the power of a positive or
negative single digit integer less than 7 and greater than -7.
hopefully this is right :/
